- added processors k8-sse3, opteron-sse3, athlon64-sse3, amdfam10, and
barcelona with appropriate sse3/4a levels
- added FeatureSSE4A for amdfam10 processors
in X86Subtarget:
- added hasSSE4A
- updated AutoDetectSubtargetFeatures to detect SSE4A
- updated GetCurrentX86CPU to detect family 15 with sse3 as k8-sse3 and
family 10h as amdfam10
New processor names match those used by gcc.

pthreads, otherwise ar complains of unresolved references to pthread_mutex_*.
LTO doesn't actually use pthreads, but ManagedStatic does.
Fix this by linking in LIBS (that contains pthreads) for LTO and gold.
For now this links in more libs than needed (libffi for example), we can figure
out later how to link in those libs per-tool later.

an integral constant expression, maintain a cache of the value and the
is-an-ICE flag within the VarDecl itself. This eliminates
exponential-time behavior of the Fibonacci template metaprogram.

entries as there are basic blocks in the function. LiveVariables::getVarInfo
creates a VarInfo struct for every register in the function, leading to
quadratic space use. This patch changes the BitVector to a SparseBitVector,
which doesn't help the worst-case memory use but does reduce the actual use in
very long functions with short-lived variables.

that of the LHS. It doesn't matter for correctness, but the LHS
is more likely than the RHS to be a pointer type in exotic cases,
and it's more tidy to have it return the integer type.

thing for non-aggregate types.
- Otherwise we unnecessarily pin values to the stack and currently end up
triggering a backend bug in one case.
- This loose cooperation with LLVM to implement the ABI is pretty ugly.

argument. This avoids the argument from being silenced when the argument is
the NULL macro, which is defined in a system header. This also makes the output
a bit nicer, e.g.:
t.c:8:3: warning: null passed to a callee which requires a non-null argument
func1(NULL, cp2, i1);
^ ~~~~
vs something like:
t.c:8:10: warning: argument is null where non-null is required
func1(NULL, cp2, i1);

1. When we accept "#garbage" in asm-with-cpp mode, change the token kind
of the # to unknown so that the preprocessor won't try to process it as
a real #. This fixes a crash on the attached example
2. Fix macro definition extents processing to handle #foo at the end of a
macro to say the definition ends with the foo, not the #.
This is a follow-on fix to r72283, and rdar://6916026

linear instruction simplification stages or not, so I left it in.
