Daniel Hoekwater	6b62166b4c	Account for PATCHABLE instrs in Branch Relaxation ... PATCHABLE_* instructions expand to up to 36-byte sleds. Updating the size of PATCHABLE instructions causes them to be outlined, so we need to add a check to prevent the outliner from considering basic blocks that contain PATCHABLE instructions.

Fangrui Song	a6a07a514b	[MachineOutliner] Don't outline functions starting with PATCHABLE_FUNCTION_ENTER/FENTRL_CALL ... MachineOutliner may outline a "patchable-function-entry" function whose body has a TargetOpcode::PATCHABLE_FUNCTION_ENTER MachineInstr. This is incorrect because the special code sequence must stay unchanged to be used at run-time. Avoid outlining PATCHABLE_FUNCTION_ENTER. While here, avoid outlining FENTRY_CALL too (which doesn't reproduce currently) to allow phase ordering flexibility.
