%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.

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).

Also fixed up code to fully use the SoImm field for ADR on ARM mode.

llvm-svn: 76890

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.

 - 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.

Fix frame index elimination to correctly handle thumb-2 addressing modes that don't allow negative offsets. During frame elimination convert *i12 opcode to a *i8 when necessary due to a negative offset.

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.

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.

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).
