Add WinLinkDriver and connect it to the existing COFF reader. Remaining
parts are still stubs, so while it can now read a COFF file, it still
cannot link or output PE/COFF files yet.

The size reduction in the RegDiffLists are rather dramatic. Here are a few
size differences for MCTargetDesc.o files (before and after) in bytes:
R600 - 36160B - 11184B - 69% reduction
ARM - 28480B - 8368B - 71% reduction
Mips - 816B - 576B - 29% reduction
One side effect of dynamically computing the aliases is that the iterator does
not guarantee that the entries are ordered or that duplicates have been removed.
The documentation implies this is a safe assumption and I found no clients that
requires these attributes (i.e., strict ordering and uniqueness).
My local LNT tester results showed no execution-time failures or significant
compile-time regressions (i.e., beyond what I would consider noise) for -O0g,
-O2 and -O3 runs on x86_64 and i386 configurations.

Giving a timeout for the call to NSPrintForDebugger() that happens when you “po” objects
This is a temporary workaround until a more detailed solution to the general problem of canceling actions is found

In addition to enabling more code reuse, this suppresses some false positives by allowing us to
compare an element region to its base. See the ptr-arith.cpp test cases for an example.

Extend LinkModules to pass a ValueMaterializer to RemapInstruction and friends to lazily create Functions for lazily linked globals. This is a big win when linking small modules with large (mostly unused) library modules.

With this patch, we create all tokens in one go before parsing and pass
an ArrayRef<FormatToken*> to the UnwrappedLineParser. The
UnwrappedLineParser is switched to use pointer-to-token internally.
The UnwrappedLineParser still copies the tokens into the UnwrappedLines.
This will be fixed in an upcoming patch.

This patch adds support for the CRJ and CGRJ instructions. Support for
the immediate forms will be a separate patch.
The architecture has a large number of comparison instructions. I think
it's generally better to concentrate on using the "best" comparison
instruction first and foremost, then only use something like CRJ if
CR really was the natual choice of comparison instruction. The patch
therefore opportunistically converts separate CR and BRC instructions
into a single CRJ while emitting instructions in ISelLowering.

To fully support this, we also need to expand tabs in the text before
the block comment. This patch breaks indentation when there was a
non-standard mixture of spaces and tabs used for indentation, but
fixes a regression in the simple case:
{
/*
* Comment.
*/
int i;
}
Is now formatted correctly, if there were tabs used for indentation
before.
llvm-svn: 182760
Block comment indentation of empty lines regressed, as we did not
have a test for it.
/* Comment with...
*
* empty line. */
is now formatted correctly again.

Before:
int (*func)(void*);
void f() { int(*func)(void*); }
After (consistent space after "int"):
int (*func)(void*);
void f() { int (*func)(void*); }

This gets turned into two ">" operators at the beginning in order to
simplify template parameter handling. Thus, we need a special case to
handle those two binary operators correctly.
With this patch, clang-format can now correctly handle cases like:
aaaaaa = aaaaaaa(aaaaaaa, // break
aaaaaa) >>
bbbbbb;

The coercion type serves two purposes:
1. Pad structs to a multiple of 64 bits, so they are passed
'left-aligned' in registers.
2. Expose aligned floating point elements as first-level elements, so
the code generator knows to pass them in floating point registers.
We also compute the InReg flag which indicates that the struct contains
aligned 32-bit floats. This flag is used by the code generator to pick
the right registers.

- All integer arguments smaller than 64 bits are extended.
- Large structs are passed indirectly, not using 'byval'.
- Structs up to 32 bytes in size are returned in registers.
Some things are not implemented yet:
- EmitVAArg can be implemented in terms of the va_arg instruction.
- When structs are passed in registers, float members require special
handling because they are passed in the floating point registers.
- Structs are left-aligned when passed in registers. This may require
padding.

This option is used to select a dynamic loader prefix to be used
at runtime. Currently this is implemented for the Linux toolchain.

When -ffast-math is in effect (on Linux, at least), clang defines
__FINITE_MATH_ONLY__ > 0 when including <math.h>. This causes the
preprocessor to include <bits/math-finite.h>, which renames the sqrt functions.
For instance, "sqrt" is renamed as "__sqrt_finite".
This patch adds the 3 new names in such a way that they will be treated
as equivalent to their respective original names.

Unify handling of whitespace when breaking protruding tokens with other
whitespace replacements.
As a side effect, the BreakableToken structure changed significantly:
- have a common base class for single-line breakable tokens, as they are
much more similar
- revamp handling of multi-line comments; we now calculate the
information about lines in multi-line comments similar to normal
tokens, and always issue replacements
As a result, we were able to get rid of special casing of trailing
whitespace deletion for comments in the whitespace manager and the
BreakableToken and fixed bugs related to tab handling and escaped
newlines.

UseAuto used to replace declarion lists with new expressons where some
variable were not initialized with new.
This fix checks that every DeclStmt has a VarDecl with an initializer and it
also ensures that all declarations have the same type.
Added tests for multiple declarations and for typedefs.
