- This also fixes a dereference of std::string::end, which makes MSVC unhappy and was causing all the static analyzer clang tests to fail.

static const class member into each translation unit, with external linkage???
- If someone understands this issue better, please clue me in, I haven't
consulted the standard yet.

This is designed for tracking a value even when it might move (like WeakVH), but it is an error to delete the referenced value (unlike WeakVH0. TrackingVH is templated like AssertingVH on the tracked Value subclass, it is an error to RAUW a tracked value to an incompatible type.
For implementation reasons the latter error is only diagnosed on accesses to a mis-RAUWed TrackingVH, because we don't want a virtual interface in a templated class.
The former error is also only diagnosed on access, so that clients are allowed to delete a tracked value, as long as they don't use it. This makes it easier for the client to reason about destruction.

Block.h/Block_private.h headers, since clients won't know what to
set. These are moved into runtime.c as appropriate
2) Use cmake checks for CAS builtins, instead of guessing based on GCC
#defines (which aren't set by clang and llvm-gcc anyway)
3) "#pragma mark" isn't supported by FSF gcc, so "#if 0" it out. It
should still show up in IDEs that support it
4) Fix some compiler warnings. GCC 4.3.3 seems super strict about
%p. function pointers can't be cast to void * either.
5) Avoid a warning for apple_versioning.c that "ISO C does not allow
empty files"

%S0<def> = EXTRACT_SUBREG %Q0<kill>, 1
to
%S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>
Implicit_def does not *read* any register so the operand should be marked "implicit". The missing "implicit" marker on the operand is wrong, but it doesn't actually break anything.

Several of the existing methods were identical to their respective
specializations, and so have been removed entirely. Several more 'leaf'
optimizations were introduced.
The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

integer pointer. For now just invalidate the fields of the struct.
This addresses: <rdar://problem/7185607> [RegionStore] support invalidation of bit fields using integer assignment

take into consideration that the result of an invoke is only valid in
the normal dest, not the unwind dest. This caused 'PHINode::hasConstantValue'
to return true in an invalid situation, causing mem2reg to delete a phi that
was actually needed. This caused a crash building 483.xalancbmk.

variable increment / decrement slighter high priority.
This has major impact on some micro-benchmarks. On MultiSource/Applications
and spec tests, it's a minor win. It also reduce 256.bzip instruction count
by 8%, 55 on 164.gzip on i386 / Darwin.

a nested-name-specifier that describes how to refer to that name. For
example, given:
struct Base { int member; };
struct Derived : Base { int member; };
the code-completion result for a member access into "Derived" will
provide both "member" to refer to Derived::member (no qualification needed) and
"Base::member" to refer to Base::member (qualification included).

enumerators when either the user intentionally wrote a qualified name
(in which case we just use that nested-name-specifier to match
the user's code) or when this is the first "case" statement and we
need a qualified name to refer to an enumerator in a different scope.

And fix a bug with the behavior of min/max instructions formed from
fcmp uge comparisons.
Also, use FiniteOnlyFPMath() for this code instead of UnsafeFPMath,
as it is more specific.
