Sanjay Patel 97c2c108fd [x86] avoid printing unnecessary sign bits of hex immediates in asm comments (PR20347) 
It would be better to check the valid/expected size of the immediate operand, but this is
generally better than what we print right now.

James Y Knight 7c905063c5 Make utils/update_llc_test_checks.py note that the assertions are 
autogenerated.

Also update existing test cases which appear to be generated by it and
weren't modified (other than addition of the header) by rerunning it.

Simon Pilgrim c1a46b729b [DAGCombiner] Vector constant folding for comparisons 
This patch adds support for vector constant folding of integer/float comparisons.

This requires FoldConstantVectorArithmetic to support scalar constant operands (in this case ISD::CONDCASE). In future we should be able to support other scalar constant types as necessary (and possibly start calling FoldConstantVectorArithmetic for all node creations)

Nadav Rotem e649d66552 Fix pr11193. 
SHL inserts zeros from the right, thus even when the original
sign_extend_inreg value was of 1-bit, we need to sra.

Nadav Rotem d315157f12 1. Fix the widening of SETCC in WidenVecOp_SETCC. Use the correct return CC type. 
2. Fix a typo in CONCAT_VECTORS which exposed the bug in #1.
