79bb6dd363 Teach ARMLoadStoreOptimizer to remove kill flags from merged instructions as well.
This is necessary to avoid a crash in certain tangled situations where a kill
flag is first correctly moved to a merged instruction, and then needs to be
moved again:

  STR %R0, a...
  STR %R0<kill>, b...

First becomes:

  STR %R0, b...
  STM a, %R0<kill>, ...

and then:

  STM a, %R0, ...
  STM b, %R0<kill>, ...

We can now remove the kill flag from the merged STM when needed. 8960050.

d3526eab46 Ignore DBG_VALUE machine instructions while constructing instruction ranges based on location info.
Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools.

eb9f040f0d Move more fragments of spill weight calculation into CalcSpillWeights.h
Simplify the spill weight calculation a bit by bypassing
getApproximateInstructionCount() and using LiveInterval::getSize() directly.
This changes the computed spill weights, but only by a constant factor in each
function. It should not affect how spill weights compare against each other, and
so it shouldn't affect code generation.

a2b6e4151b Fix encoding and add parsing support for the arm/thumb CPS instruction:
- Add custom operand matching for imod and iflags.
- Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC
  from mnemonic.
- While adding ".w" as an operand, don't change "Head" to avoid passing the
  wrong mnemonic to ParseOperand.
- Add asm parser tests.
- Add disassembler tests just to make sure it can catch all cps versions.

what StringRef is to strings.

0a9481f44f Enhance ComputeMaskedBits to know that aligned frameindexes
have their low bits set to zero.  This allows us to optimize
out explicit stack alignment code like in stack-align.ll:test4 when
it is redundant.

Doing this causes the code generator to start turning FI+cst into
FI|cst all over the place, which is general goodness (that is the
canonical form) except that various pieces of the code generator
don't handle OR aggressively.  Fix this by introducing a new
SelectionDAG::isBaseWithConstantOffset predicate, and using it
in places that are looking for ADD(X,CST).  The ARM backend in
particular was missing a lot of addressing mode folding opportunities
around OR.

yet this unfortunately doesn't have much effect in the testsuite.
