Summary: Add support for LLVM_USE_SANITIZER to the libc++abi tests. Currently, if libc++abi is configured with LLVM_USE_SANITIZER then none of the tests will pass.

Clang 3.6 no longer links the sanitizer runtime library dependancies when
-nodefaultlibs is used. This patch manually links in a missing dependancy.

This tool lets us build LLVM components within the tree by setting up a
$GOPATH that resembles a tree fetched in the normal way with "go get".
It is intended that components such as the Go frontend will be built in-tree
using this tool.

This was not a real header role, and was never exposed to clients of ModuleMap.
Remove the enumeration value for it and track it as marking the header as
'known' rather than creating an extra KnownHeader entry that *every single*
client ignores.

This is a sad thing to do, but all the alternatives look ugly.
Looks like there are legitimate cases when users may want to link
with sanitizer runtimes *and* -nodefaultlibs (and ensure they provide
replacements for system libraries). For example, this happens in libc++
test suite.
"-nodefaultlibs" is told to link only the libraries explicitly provided
by the user, and providing "-fsanitize=address" is a clear indication of
intention to link with ASan runtime.
We can't easily introduce analogue of "-print-libgcc-name": linking with
sanitizers runtimes is not trivial: some runtimes are split into several
archive libraries, which are required to be wrapped in
-whole-archive/-no-whole-archive.
If "-fsanitize=whatever" and "-nodefaultlibs" are provided, system library
dependencies of sanitizer runtimes (-lc/-ldl/-lpthread/-lrt) will *not* be
linked, and user would have to link them in manually. Note that this can
cause problems, as failing to provide "-lrt" might lead to crashes in runtime
during ASan initialization. But looks like we should bite this bullet.
See r218541 review thread for the discussion.

Variable handling will be sunk into DwarfFile so that abstract variables
and the like can be shared across multiple CUs (to handle cross-CU
inlining, for example).

Use the DwarfDebug in one function that previously took it as a
parameter, and lay the foundation for use this for other operations
coming soon.

Now that we're sure the only root (non-abstract) scope is the current
function scope, there's no need for isCurrentFunctionScope, the property
can be tested directly instead.

This allows a module to specify that it logically contains a file, but that
said file is non-modular and intended for textual inclusion. This allows
layering checks to work properly in the presence of such files.

The description of the parameter value passed to -enable-polly-aligned did
not make any sense at all, but was just a leftover coming from when this option
was copied form -enable-polly-openmp. We just drop it as the option description
gives sufficient information already.

MCJIT::getPointerForFunction adds the resulting address to the global mapping.
This should be done via updateGlobalMapping rather than addGlobalMapping, since
the latter asserts if a mapping already exists.
MCJIT::getPointerToFunction is actually deprecated - hopefully we can remove it
(or more likely re-task it) entirely soon. In the mean time it should at least
work as advertised.

This makes sure we consistently use dbgs() when printing debug output.
Previously, the code just mixed calls to isl_*_dump() with printing to dbgs()
and was relying for both methods to interact in predictable ways (same output
stream, no unexpected reordering of outputs).
llvm-svn: 220443
By adding braces into the DEBUG statement we can make clang-format format code
such as:
DEBUG(stmt1(); stmt2())
as multi-line code:
DEBUG({
stmt1();
stmt2();
});
This makes control-flow in debug statements easier to read.

Summary:
Currently when emitting a label, a new data fragment is created for it if the
current fragment isn't a data fragment.
This change instead enqueues the label and attaches it to the next fragment
(e.g. created for the next instruction) if possible.
When bundle alignment is not enabled, this has no functionality change (it
just results in fewer extra fragments being created). For bundle alignment,
previously labels would point to the beginning of the bundle padding instead
of the beginning of the emitted instruction. This was not only less efficient
(e.g. jumping to the nops instead of past them) but also led to miscalculation
of the address of the GOT (since MC uses a label difference rather than
emitting a "." symbol).

To do this, I fixed the CPPLanguageRuntime::StripNamespacesFromVariableName() function to use a regular expression that correctly determines if the name passed to it is a qualfied C++ name like "a:🅱️:c" or "b::c". The old version of this function was treating '__54-[NSUserScriptTask executeWithInterpreter:arguments::]_block_invoke' as a match with a basename of ']_block_invoke'.
Also fixed a case in the by name lookup of functions where we wouldn't look for the full name if we actually tried to call CPPLanguageRuntime::StripNamespacesFromVariableName() and got an empty basename back.

When a user has not configured a standard Visual Studio environment
by running vcvarsall, clang tries its best to find Visual Studio
include files and executables anyway. This patch makes clang also
try to find system and Windows SDK libraries for linking against,
as well.

This resubmits change r220226. That change broke the chromium
build bots because chromium it ships an hermetic MSVC toolchain
that it expects clang to fallback to by finding it on the path.
This patch fixes the issue by bumping up the prioritization of PATH
when looking for MSVC binaries.

This patch changes the RegionSet type used in ScopDetection from a
std::set to a llvm::SetVector. The reason for the change is to
ensure deterministic output when printing the result of the
analysis. We had a windows buildbot failure for the modified test
because the output was coming in a different order.
Only one test case needed to be modified for this change. We could
use CHECK-DAG directives instead of CHECK in the analysis test cases
because the actual order of scops does not matter, but I think that
change should be done in a separate patch that modifies all the
appliciable tests. I simply modified the test to reflect the
expected deterministic output.

It's not clear how this would be tested - I imagine we should have an
ASTImporter test that RAVs the new AST and checks that all the elements
in it are from this ASTContext and not the foreign one... but I know
little about the ASTImporter and how/where that testing might be done.

This would cause the flag to appear in the output of "llvm-config --cppflags",
which should contain only preprocessor flags. The -gsplit-dwarf flag in
particular can cause problems with certain downstream users such as cgo.
