Joerg Sonnenberger 002a14765e Enabling thumb2 mode used to force support for armv6t2. Replace this
with a temporary assertion and adjust the various test cases.

Stephen Lin f799e3f944 Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion.
This was done with the following sed invocation to catch label lines demarking function boundaries:
    sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll
which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct.

Jim Grosbach ca7eaaafda When using the 'push' mnemonic for Thumb2 stmdb, be explicit when it's the
32-bit wide version by adding the .w suffix.

Jim Grosbach 7a6c37d3e7 Teach the (non-MC) instruction printer to use the cannonical names for push/pop,
and shift instructions on ARM. Update the tests to match.

Bob Wilson 298a83ecfe Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.
This does not move entirely to UAL syntax, since the default "increment after"
suffix is empty but we still use "IA" for that.

Anton Korobeynikov 75dfed4fa5 Dynamic stack realignment use of sp register as source/dest register
in "bic sp, sp, #15" leads to unpredicatble behaviour in Thumb2 mode.
Emit the following code instead:
mov r4, sp
bic r4, r4, #15
mov sp, r4

Evan Cheng b972e5633f It turns out most of the thumb2 instructions are not allowed to touch SP. The semantics of such instructions are unpredictable. We have just been lucky that tests have been passing.
This patch takes pain to ensure all the PEI lowering code does the right thing when lowering frame indices, insert code to manipulate stack pointers, etc. It's also custom lowering dynamic stack alloc into pseudo instructions so we can insert the right instructions at scheduling time.

This fixes PR4659 and PR4682.

Evan Cheng 780748d565 - More refactoring. This gets rid of all of the getOpcode calls.
- This change also makes it possible to switch between ARM / Thumb on a
  per-function basis.
- Fixed thumb2 routine which expand reg + arbitrary immediate. It was using
  using ARM so_imm logic.
- Use movw and movt to do reg + imm when profitable.
- Other code clean ups and minor optimizations.
