Chandler Carruth f2113f3b48 Add range erase, element insert, and range insert methods to
TinyPtrVector. With these, it is sufficiently functional for my more
normal / pedestrian uses.

I've not included some r-value reference stuff here because the value
type for a TinyPtrVector is, necessarily, just a pointer.

I've added tests that cover the basic behavior of these routines, but
they aren't as comprehensive as I'd like. In particular, they don't
really test the iterator semantics as thoroughly as they should. Maybe
some brave soul will feel enterprising and flesh them out. ;]

Nick Kledzik 5fce8c4ffe Initial commit of new FileOutputBuffer support class.
Since the llvm::sys::fs::map_file_pages() support function it relies on
is not yet implemented on Windows, the unit tests for FileOutputBuffer 
are currently conditionalized to run only on unix.

Chandler Carruth 94ed210702 Implement copy and move assignment for TinyPtrVector. These try to
re-use allocated vectors as much as possible.

Chandler Carruth a565375a18 Bring TinyPtrVector under test. Somehow we never picked up unit tests
for this class. These tests exercise most of the basic properties, but
the API for TinyPtrVector is very strange currently. My plan is to start
fleshing out the API to match that of SmallVector, but I wanted a test
for what is there first.

Sadly, it doesn't look reasonable to just re-use the SmallVector tests,
as this container can only ever store pointers, and much of the
SmallVector testing is to get construction and destruction right.

Just to get this basic test working, I had to add value_type to the
interface.

While here I found a subtle bug in the combination of 'erase', 'begin',
and 'end'. Both 'begin' and 'end' wanted to use a null pointer to
indicate the "end" iterator of an empty vector, regardless of whether
there is actually a vector allocated or the pointer union is null.
Everything else was fine with this except for erase. If you erase the
last element of a vector after it has held more than one element, we
return the end iterator of the underlying SmallVector which need not be
a null pointer. Instead, simply use the pointer, and poniter + size()
begin/end definitions in the tiny case, and delegate to the inner vector
whenever it is present.

Chandler Carruth 0b01261cb0 Move the SmallVector unit tests to be type-parameterized so that we can
test more than a single instantiation of SmallVector.

Add testing for 0, 1, 2, and 4 element sized "small" buffers. These
appear to be essentially untested in the unit tests until now.

Fix several tests to be robust in the face of a '0' small buffer. As
a consequence of this size buffer, the growth patterns are actually
observable in the test -- yes this means that many tests never caused
a grow to occur before. For some tests I've merely added a reserve call
to normalize behavior. For others, the growth is actually interesting,
and so I captured the fact that growth would occur and adjusted the
assertions to not assume how rapidly growth occured.

Also update the specialization for a '0' small buffer length to have all
the same interface points as the normal small vector.

Chandler Carruth f5fe556c70 Add support for attaching branch weight metadata directly from the IRBuilder.
Added a basic unit test for this with CreateCondBr. I didn't go all the
way and test the switch side as the boilerplate for setting up the
switch IRBuilder unit tests is a lot more. Fortunately, the two share
all the interesting code paths.

Chandler Carruth 36e2ecf528 Move llvm/Support/TypeBuilder.h -> llvm/TypeBuilder.h. This completes
the move of *Builder classes into the Core library.

No uses of this builder in Clang or DragonEgg I could find.

If there is a desire to have an IR-building-support library that
contains all of these builders, that can be easily added, but currently
it seems likely that these add no real overhead to VMCore.

Chandler Carruth ec7ad6561f Move llvm/Support/MDBuilder.h to llvm/MDBuilder.h, to live with
IRBuilder, DIBuilder, etc.

This is the proper layering as MDBuilder can't be used (or implemented)
without the Core Metadata representation.

Patches to Clang and Dragonegg coming up.

Chandler Carruth aafe0918bc Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.h
This was always part of the VMCore library out of necessity -- it deals
entirely in the IR. The .cpp file in fact was already part of the VMCore
library. This is just a mechanical move.

I've tried to go through and re-apply the coding standard's preferred
header sort, but at 40-ish files, I may have gotten some wrong. Please
let me know if so.

I'll be committing the corresponding updates to Clang and Polly, and
Duncan has DragonEgg.

Thanks to Bill and Eric for giving the green light for this bit of cleanup.

Bill Wendling e38859dc8e Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h.

The reasoning is because the DebugInfo module is simply an interface to the
debug info MDNodes and has nothing to do with analysis.

Chandler Carruth 94d0251824 Completely refactor the structuring of unittest CMake files to match the
Makefiles, the CMake files in every other part of the LLVM tree, and
sanity.

This should also restore the output tree structure of all the unit
tests, sorry for breaking that, and thanks for letting me know.

The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages:

- No more weird directory stripping in the unittest macro, allowing it
  to be used more readily in other projects.
- No more directory prefixes on all the source files.
- Allows correct and precise use of LLVM's per-directory dependency
  system.
- Allows use of the checking logic for source files that have not been
  added to the CMake build. This uncovered a file being skipped with
  CMake in LLVM and one in Clang's unit tests.
- Makes Specifying conditional compilation or other custom logic for JIT
  tests easier.

It did require adding the concept of an explicit 'optional' source file
to the CMake build so that the missing-file check can skip cases where
the file is *supposed* to be missing. =]

This is another chunk of refactoring the CMake build in order to make it
usable for other clients like CompilerRT / ASan / TSan.

Note that this is interdependent with a Clang CMake change.

Chandler Carruth e530d2ba4d Remove one of the LLVM-specific CMake hacks in favor of standard CMake

This was only used in one place in LLVM, and was used pervasively (but
with different code!) in Clang. It has no advantages over the standard
CMake facilities and in some cases disadvantages.

Chandler Carruth 35e6706675 Fix inappropriate use of anonymous namespaces in unittests.
The TEST_F macros actually declare *subclasses* of the test fixtures.
Even if they didn't we don't want them to declare external functions.
The entire unit test, including both the fixture class and the fixture
test cases should be wrapped in the anonymous namespace.

This issue was caught by the new '-Winternal-linkage-in-inline' warning.

Chandler Carruth 198422a475 Fix PR13148, an inf-loop in StringMap.
StringMap suffered from the same bug as DenseMap: when you explicitly
construct it with a small number of buckets, you can arrange for the
tombstone-based growth path to be followed when the number of buckets
was less than '8'. In that case, even with a full map, it would compare
'0' as not less than '0', and refuse to grow the table, leading to
inf-loops trying to find an empty bucket on the next insertion. The fix
is very simple: use '<=' as the comparison. The same fix was applied to
DenseMap as well during its recent refactoring.

Thanks to Alex Bolz for the great report and test case. =]

First, make it parse cleanly. Yay for uninstantiated methods.
