operands of other instructions.

Make Extract128BitVector and Insert128BitVector take an unsigned instead of an ConstantNode SDValue. getConstant was almost always called just before only to have the functions take it apart and build a new ConstantSDNode.

Remove unnecessary StringRef->char*->StringRef conversion, which read uninitialized memory if the input wasn't 0-terminated.

Make calls to getVectorShuffle more consistent. Use shuffle VT for calls to getUNDEF instead of requerying. Use &Mask[0] instead of Mask.data().

Simplify code by converting multiple places that were manually concatenating 128-bit vectors to use either CONCAT_VECTORS or a helper function. CONCAT_VECTORS will itself be lowered to the same pattern as before. The helper function is needed for concats of BUILD_VECTORs since getNode(CONCAT_VECTORS) will just return a large BUILD_VECTOR and we may be trying to lower large BUILD_VECTORS when this occurs.

1) Make the checked assertions a bit more precise. We really want the
   canonical forms coming out of reassociate to be exactly what is
   expected.
2) Remove other passes, and switch the test to actually directly check
   that reassociate makes the important transforms and
   canonicalizations.
3) Fold in a related test case now that we're using FileCheck. Make the
   same tidying changes to it.

pretend there was no previous declaration -- that can lead us to injecting
a class template (with no access specifier) into a class scope. Instead,
just avoid the problematic checks.

It set NumLowBitAvailable = 3 which may not be true on all platforms.  We only
ever use 2 bits (the default) so this assumption can be safely removed

Should fix PR12612.
