Recommit "[ConstraintElim] Enable pass by default."
This reverts commit 695ce48c63ec582a46bfbda9b066f4d3bcde143f. The compile-time regression causing the revert has been fixed. Recommit the original patch. Original commit message: The pass should help to close a functional gap when it comes to reasoning about related conditions in a relatively general way. It addresses multiple existing issues (linked below) and the need for a more powerful reasoning system was also discussed recently in https://discourse.llvm.org/t/rfc-alternative-approach-of-dealing-with-implications-from-comparisons-through-pos-analysis/65601/7 On AArch64, the new pass performs ~2000 simplifications on MultiSource,SPEC2006,SPEC2017 with -O3.
