f9affc1dc9 lit/TestingConfig.py: Add the environment variable PRINTF_EXPONENT_DIGITS as workaround [PR6745] for mingw's tests. Danil Malyshev suggested this. 
FIXME: It does not improve MSVC's issue.

[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

8965ba39fb The change for PR9190 wasn't quite right. We need to avoid making the 
transformation if we can't legally create a build vector of the correct
type. Check that we can make the transformation first, and add a TODO to
refactor this code with similar cases.

d8c18daea5 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.

d5b7c28519 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.

70f48f08c1 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.

e53a0cef51 PR9139: Specify ARM/Darwin triple for vector-DAGCombine.ll test.

e65a98b127 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.
