Summary:
Also ran clang-format on the function. The code added is the last else
if block.

comment of the API.
Relaxes the behavior of TargetInstrInfo::commuteInstruction when
TargetInstrInfo::findCommutedOpIndices returns false.
Previously TargetInstrInfo triggered a fatal error in such situation whereas based
on the comment in the API it should just return nullptr. Indeed the only
precondition that should be ensured is that the instruction must be commutable.

On reflection, this is better despite the missing command-line handling
bits for remarks. Making this a remark makes it much clearer that
this is purely informational and avoids the negative connotations of a
'warning'.

(r207876 was reverted in r208131 after seeing some consistent buildbot
failure for MSVC 2012. The original commits were in r207724-r207726)
Takumi was nice enough to dig into this and locate this Microsoft

describing a bug in MSVC2012's forward_as_tuple implementation.
Since the parameters in this instance are trivial/small, pass them by
value (using make_tuple) instead of perfectly-forwarded tuple of rvalue
references (involving the broken forward_as_tuple). Hopefully this will
satisfy MSVC2012.

This behavior was added to support StringMaps of StringMaps, default +
move construction are sufficient for this.
Real move construction support coming soon (& probably copy construction
too).

Sorry for the commit spam. My clang-format crashed on me and the vim
plugin did not print an error, but instead just left the formatting
untouched.

This warning is too noisy and doesn't really indicate a problem for most
people. Even though it would only really affect people using
-Weverything, that seems bad so remove it.

This patch teaches the backend how to combine packed SSE2/AVX2 arithmetic shift
intrinsics.
The rules are:
- Always fold a packed arithmetic shift by zero to its first operand;
- Convert a packed arithmetic shift intrinsic dag node into a ISD::SRA only if
the shift count is known to be smaller than the vector element size.
This patch also teaches to function 'getTargetVShiftByConstNode' how fold
target specific vector shifts by zero.
Added two new tests to verify that the DAGCombiner is able to fold
sequences of SSE2/AVX2 packed arithmetic shift calls.

When building on Windows, the default target is Windows. Windows on ARM does
not support ARM mode compilation, resulting in test failures. Simply specify a
triple to ensure that we are testing the correct behaviour.

Large is CodeModel::Model::Large, not CodeModel::Model::Medium. Thanks to
majnemer for pointing out the typo! Its unclear how to test the mapped value in
the compiler, the tests already cover the driver side.
