Fangrui Song	f17ae668a9	[Driver][CodeGen] Add -fpatchable-function-entry=N[,0] ... In the backend, this feature is implemented with the function attribute "patchable-function-entry". Both the attribute and XRay use TargetOpcode::PATCHABLE_FUNCTION_ENTER, so the two features are incompatible.

Fangrui Song	a44c434b68	Support function attribute patchable_function_entry ... This feature is generic. Make it applicable for AArch64 and X86 because the backend has only implemented NOP insertion for AArch64 and X86.
