[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

[X86] Override BuildSDIVPow2 for X86. As noted in PR43197, we can use test+add+cmov+sra to implement signed division by a power of 2. This is based off the similar version in AArch64, but I've adjusted it to use target independent nodes where AArch64 uses target specific CMP and CSEL nodes. I've also blocked INT_MIN as the transform isn't valid for that. I've limited this to i32 and i64 on 64-bit targets for now and only when CMOV is supported. i8 and i16 need further investigation to be sure they get promoted to i32 well. I adjusted a few tests to enable cmov to demonstrate the new codegen. I also changed twoaddr-coalesce-3.ll to 32-bit mode without cmov to avoid perturbing the scenario that is being set up there.
