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

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.

regardless of the architecture).
 - This is a good default for development & testing; for example without this
   any tests using 'clang' in the test suite will fail on PowerPC, since the
   driver will avoid using clang.

 - We don't want to actually ship something built this way, but that should be
   handled via some sort of configuration file.

We don't need to keep track of the packed alignment, just whether the struct is packed or not. Fixes PR4610.

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.

_a:

_b:
	cmpunordps	%xmm1, %xmm0

Use arrays as union padding. Also, since the resulting struct will always contain a single element and either a single i8 element or an array of i8s, there's no reason to use a packed struct.

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).
