c205a8da9d Update insertps handling based on feedback. Move to a v4f32 style 
to support vector arguments and scalar arguments correctly. Update
lowering and fix comment to refer to pinsr* instead of insertps.

bbcb16a3eb "fix" PR4612, which is a crash on: 
%0 = malloc [3758096384 x i32]

The "malloc" instruction doesn't support 64-bits correctly (see PR715),
and should be removed.  Victor is actively working on fixing this, in 
the meantime just don't crash.

f4838d90e4 Revert r75581: it causes massive breakage in the Ada 
testsuite, due to exception handling not working
correctly.  Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday.  Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc.  This is a
nasty flaw in the nightly testers.  (On the other
hand the Ada testsuite links with the just built
libgcc).

8997f6bfc1 Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address. 
Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.

b5adc13728 Convert StringMap to using StringRef for its APIs. 
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

f0462da445 Cache dependence computation using FoldingSet. 
This introduces an LDA-internal DependencePair class. The intention is,
that this is a place where dependence testers can store various results
such as SCEVs describing conflicting iterations, breaking conditions,
distance/direction vectors, etc.

c687344f0c Make some existing optimizations that would only trigger on scalars 
also apply to vectors.  This allows us to compile this:

#include <emmintrin.h>
__m128i a(__m128 a, __m128 b) { return a==a & b==b; }
__m128i b(__m128 a, __m128 b) { return a!=a | b!=b; }

to:

_a:
	cmpordps	%xmm1, %xmm0
	ret
_b:
	cmpunordps	%xmm1, %xmm0
	ret

with clang instead of to a ton of horrible code.

313c95ea84 change a test to run in filecheck style. Rename it to be a general 
dumping ground of various SSE4.1 tests, since filecheck can reasonably
handle them all in one file.  Generalize it to check x86-64 stuff as
well since it has a different ABI (a convenient way to test both the 
reg and mem forms of these instructions).
