d4aaabfa74 Revert 113679, it was causing an infinite loop in a testcase that I've sent 
on to Owen.

d4ebde12ce Invert and-of-or into or-of-and when doing so would allow us to clear bits of the and's mask. 
This can result in increased opportunities for store narrowing in code generation.  Update a number of
tests for this change.  This fixes <rdar://problem/8285027>.

Additionally, because this inverts the order of ors and ands, some patterns for optimizing or-of-and-of-or
no longer fire in instances where they did originally.  Add a simple transform which recaptures most of these
opportunities: if we have an or-of-constant-or and have failed to fold away the inner or, commute the order 
of the two ors, to give the non-constant or a chance for simplification instead.

6110efbf8c Teach InstructionSimplify to fold (A & B) & A -> A & B and (A | B) | A -> A | B. 
Reassociate does this but it doesn't catch all cases (e.g. if the operands are i1).

01b7bf3510 Fix merging base-updates for VLDM/VSTM: Before I switched these instructions 
to use AddrMode4, there was a count of the registers stored in one of the
operands.  I changed that to just count the operands but forgot to adjust for
the size of D registers.  This was noticed by Evan as a performance problem
but it is a potential correctness bug as well, since it is possible that this
could merge a base update with a non-matching immediate.

c9cb37516d Teach if-converter to be more careful with predicating instructions that would 
take multiple cycles to decode.
For the current if-converter clients (actually only ARM), the instructions that
are predicated on false are not nops. They would still take machine cycles to
decode. Micro-coded instructions such as LDM / STM can potentially take multiple
cycles to decode. If-converter should take treat them as non-micro-coded
simple instructions.

547563df12 llvm-mc: Don't crash when using -n and we see a directive before the initial section. 
- This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution.

db6a08beef Revert r113439, which relaxed the requirement that loops containing calls cannot be unrolled. After some discussion, 
there seems to be a better way to achieve the same effect.

8849104392 Add an elf-dumper utility. 
- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.

4a66e8e24d Get rid of the last use of -m64 in FrontendC. This solution 
of checking for either 4 or 8 is not very satisfactory, but
it would catch the original problem (an alignment of 1).

3030644248 Another test that uses -m64. Here too it looks like it can be 
removed.  Not that the XTARGET wasn't doing anything since it
does nothing without an accompanying XFAIL.

e89d619d23 On i386, llvm-gcc cannot be assumed to support -m64. Since these 
tests pass here (i686-linux and x86-64-linux) without -m64, simply
remove the -m64.

524123343c Fix NEON VLD pseudo instruction itineraries that were incorrectly copied from 
the VST pseudos.  The VLD/VST scheduling still needs work (see pr6722), but
at least we shouldn't confuse the loads with the stores.

956afdd1f2 Relax the "don't unroll loops containing calls" rule. Instead, when a loop contains a call, lower the 
unrolling threshold to the optimize-for-size threshold.  Basically, for loops containing calls, unrolling
can still be profitable as long as the loop is REALLY small.

a58a97dafc Fix a serious performance regression introduced by r108687 on linux: 
turning (fptrunc (sqrt (fpext x))) -> (sqrtf x)  is great, but we have
to delete the original sqrt as well.  Not doing so causes us to do 
two sqrt's when building with -fmath-errno (the default on linux).
