Craig Topper 6dce9fbec1 [X86] Don't invert NewCC variable while processing the jcc/setcc/cmovcc instructions in optimizeCompareInstr.
The NewCC variable is calculated outside of the loop that processes jcc/setcc/cmovcc instructions. If we invert it during the loop it can cause an incorrect value to be used by a later iteration. Instead only read it during the loop and use a new variable to store the possibly inverted value.

Fixes PR35399.
