Richard Osborne fc39e417a8 Add tests for handling of globals and tls on the XCore. These currently fail
but pass when run against r76652.

Eric Christopher f37ea3ad75 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.

Chris Lattner 308c7896a4 "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.

Duncan Sands f4981105ca 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).

Evan Cheng 95a73e2eab 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.

Daniel Dunbar 5bf72e20eb 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.

Andreas Bolka c8cd3f6959 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.

Chris Lattner 7d55541e56 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.

Chris Lattner b9cdd3153c 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).
