[PATCH] D75936: Add a Pass to X86 that builds a Condensed CFG for Load Value Injection (LVI) Gadgets [4/6]

Comment at: llvm/test/CodeGen/X86/O3-pipeline.ll:147
+; CHECK-NEXT:       X86 Load Value Injection (LVI) Load Hardening
 ; CHECK-NEXT:       Fixup Statepoint Caller Saved
 ; CHECK-NEXT:       PostRA Machine Sink
----------------
I'm curious what happens if we add AU.setPreservesCFG() to getAnalysisUsage in FixupStatepointCallerSaved.cpp  From a quick look through that pass it doesn't look like it changes the Machine CFG.

PostRA Machine Sink already preserves CFG. So I think that should remove the dominator tree construction after PostRA machine sink.
