Bob Wilson a0c69014f8 Remove the install-clang-c makefile target. 
When I did this before it broke a buildbot that was testing that target, but
we've removed that buildbot now.

Daniel Dunbar 8d5cc33ad8 llvm-config: Replace with C++ version (was llvm-config-2). 
- Reapply of r144300, with lots of fixes/migration easement in between.

Evan Cheng 648e48d02e Add another missing pattern. llvm-gcc likes f64 but clang likes i64 so it was generating poor code for some SSE builtins.

Jakob Stoklund Olesen bde32d36bb Make X86::FsFLD0SS / FsFLD0SD real pseudo-instructions. 
Like V_SET0, these instructions are expanded by ExpandPostRA to xorps /
vxorps so they can participate in execution domain swizzling.

This also makes the AVX variants redundant.

Duncan Sands ca6f8ddbf8 Fix a theoretical problem (not seen in the wild): if different instances of a 
weak variable are compiled by different compilers, such as GCC and LLVM, while
LLVM may increase the alignment to the preferred alignment there is no reason to
think that GCC will use anything more than the ABI alignment.  Since it is the
GCC version that might end up in the final program (as the linkage is weak), it
is wrong to increase the alignment of loads from the global up to the preferred
alignment as the alignment might only be the ABI alignment.

Increasing alignment up to the ABI alignment might be OK, but I'm not totally
convinced that it is.  It seems better to just leave the alignment of weak
globals alone.
