[MachineOutliner] fix test for excluding CFI and add test to include CFI in outlining New test to check that we only outline CFI instruction if all CFI Instructions in the function would be captured by the outlining adding x86 tests analagous to AARCH64 cfi tests Revision: https://reviews.llvm.org/D77852

# Outlining CFI instructions is unsafe if we cannot outline all of the CFI
|
|
# instructions from a function. This shows that we choose not to outline the
|
|
# CFI instructions since function foo has a CFI Instruction that would not
|
|
# be caught.
