[x86] regenerate checks with update_llc_test_checks.py The dream of a unified check-line auto-generator for all phases of compilation is dead. The llc script has already diverged to be better at its goal, so having 2 scripts that do almost the same thing is just causing confusion. We can rip out the llc ability in update_test_checks.py next and rename it, so it will be clear that we have one script for llc check auto-generation and another for opt. llvm-svn: 305206

[DAGCombiner] fold assertzexts separated by trunc If we have an AssertZext of a truncated value that has already been AssertZext'ed, we can assert on the wider source op to improve the zext-y knowledge: assert (trunc (assert X, i8) to iN), i1 --> trunc (assert X, i1) to iN This moves a fold from being Mips-specific to general combining, and x86 shows improvements.

[DAG] add fold for masked negated extended bool The non-obvious motivation for adding this fold (which already happens in InstCombine) is that we want to canonicalize IR towards select instructions and canonicalize DAG nodes towards boolean math. So we need to recreate some folds in the DAG to handle that change in direction. An interesting implementation difference for cases like this is that InstCombine generally works top-down while the DAG goes bottom-up. That means we need to detect different patterns. In this case, the SimplifyDemandedBits fold prevents us from performing a zext to sext fold that would then be recognized as a negation of a sext. llvm-svn: 283900
