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.

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.

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.
