4dcc3bd23b Test instructions operands were printed in the wrong order.

d85f7acc83 "The MMX_MASKMOVQ and MMX_MASKMOVQ64 instructions are labeled as MRMDestMem 
instructions, which implies that there is an explicit memory operand.  There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI.  This causes the table-generation code
for the disassembler to report an error."

Patch by Sean Callanan!

9f516abaa5 This test only works on ppc32 if some optimization is done before 
generating LLVM IR; it is correct in the code as written
to use 8-byte-aligned operations to copy Key in bar.  Formerly
the gcc inliner was run, now it isn't.  I don't think it's
possible to preserve this as a pure FE test.  Adding -O2 lets
the llvm optimizers get rid of the 8-byte-aligned stores, at least.

3550840eb3 See test. Judging from PR 1278, at the time the test was committed, the 
generated code was apparently doing stores directly into the return value
aggregate; now, it's doing a copy from a compiler-generated static object.
That object is initialized using [4 x i8] which breaks the test.  I believe
this change preserves the original point of the test.

Of course it would be better for the code to do stores directly into the
return aggregate, but that is not what happens at -O0; the llvm optimizers
seem to do that on x86 but not on ppc32, possibly because of the explicit
padding (which is unavoidable).  I think it must have been being done by
a gcc optimizer pass before.

3e8033f7f7 Initial Thumb2 support. Majority of the work is done by David Goodwin. There are 
also some contribution from Jim Grosbach, Bob Wilson, and Evan Cheng.

I've done my best to consolidate the patches with those that were done by
Viktor Kutuzov and Anton Korzh from Access Softek, Inc. Let me know if missed
anything. I've completely reorganized the thumb2 td file, made more extensive
uses of multiclass, etc.

Test cases will be contributed later after I re-organize what's in svn first.
