Now that mem2reg understands how to cope with a slightly wider set of

alloca for splitting in SROA. That lets us short-circuit the common case

Reduce stack frame size by avoiding a large token vector on an error path.
Beginning with svn r186971, we noticed an internal test started to fail when
using clang built with LTO. After much investigation, it turns out that there
are no blatant bugs here, we are just running out of stack space and crashing.
Preprocessor::ReadFunctionLikeMacroArgs already has one vector of 64 Tokens,
and r186971 added another. When built with LTO, that function is inlined into
Preprocessor::HandleMacroExpandedIdentifier, which for our internal test is
invoked in a deep recursive cycle. I'm leaving the original 64 Token vector
alone on the assumption that it is important for performance, but the new
FixedArgTokens vector is only used on an error path, so it should be OK if it
requires additional heap storage. It would be even better if we could avoid
the deep recursion, but I think this change is a good thing to do regardless.

Fix yet another memory leak found by the vg-leak bot. Folks (including

The fix here is to not construct the global if we aren't going to need
it. That's cheaper anyways, and globals have highly predictable types in
practice. I've added an assert to catch skew between our manual testing
of the type and the actual type just for paranoia's sake.
Note that this pattern is actually fine in most globals because when you
build a global with a module it automatically is moved to be owned by
that module. But here, we're in isel and don't really want to do that.

all PowerPC targets, whether 32- or 64-bit. They will both implicitly
define __ppc64__ and __powerpc64__ for 64-bit PowerPC targets, and not
for 32-bit targets. We cannot be sure that all other possible
compilers used to compile Clang/LLVM define both __ppc__ and
__powerpc__, for example, so it is best to check for both when relying
on either inside the Clang/LLVM code base.
This patch makes sure we always check for both variants. In addition,
it fixes one unnecessary check in lib/Target/PowerPC/PPCJITInfo.cpp.
(At least one of __ppc__ and __powerpc__ should always be defined when
compiling for a PowerPC target, no matter which compiler is used, so
testing for them is unnecessary.)
There are some places in the compiler that check for other variants,
like __POWERPC__ and _POWER, and I have left those in place. There is
no need to add them elsewhere. This seems to be in Apple-specific
code, and I won't take a chance on breaking it.
There is no intended change in behavior; thus, no test cases are
added.

Fix up the BUILD_CLANG_ONLY code to work properly after r184794.
When BUILD_CLANG_ONLY is set to YES, it is supposed to simply limit the tools
that get built. The change in r184794 broke this feature by moving libclang
and c-index-test into PARALLEL_DIRS. Those are both supposed to be in DIRS,
because c-index-test has a build dependency on libclang and cannot be
reliably built in parallel with it.
