There is no reason to store pointers as 'void*' in CXTranslationUnitImpl, since
it does not affect libclang ABI.

Since ARM has diverging ABIs on this detail, it's probably worth
testing both it and a "normal" Itanium system.

Intended to be useful as a key associated with a unique file across
an indexing session.

When the analyzer sees an initializer, it checks if the initializer
contains a CXXConstructExpr. If so, it trusts that the CXXConstructExpr
does the necessary work to initialize the object, and performs no further
initialization.
This patch looks through any implicit wrapping expressions like
ExprWithCleanups to find the CXXConstructExpr inside.
Fixes PR15070.

The expression 'a->b.c()' contains a call to the 'c' method of 'a->b'.
We emit an error if 'a' is NULL, but previously didn't actually track
the null value back through the 'a->b' expression, which caused us to
miss important false-positive-suppression cases, including
<rdar://problem/12676053>.

"Prune" is the term for eliminating pieces of a path that are not
relevant to the user. "Suppress" means don't show that path at all.

factor the realpath calls into FileManager::getCanonicalName() so we
can cache the results of this epically slow operation. 5% speedup on
my modules test, and realpath drops out of the profile.

Title: [PR9027] volatile struct bug: member is not loaded at -O;
This is caused by last flag passed to @llvm.memcpy being false,
not honoring that aggregate has at least one 'volatile' data member
(even though aggregate itself has not been qualified as 'volatile'.
As a result, optimization optimizes away the memcpy altogether.
Patch review by John MaCall (I still need to fix up a test though).

ARM is not thinking about over-aligned structures.
Overrule ARM in both our generic-ARM and iOS ABI implementations.

know the identifier will not be found. This makes the global module
index optimization actually useful, providing an 8.5% speedup over
modules without the global module index for -fsyntax-only.

iOS ABI, which was driven by what was implemented in gcc-4.2.
However, implement it now for other ARM-based platforms.

-fsyntax-only time for modules.
With this change, we can actually see some performance different from
the global module index, but it's still about 1%.
