Kees Cook df3405245a x86/asm: Add suffix macro for GEN_*_RMWcc() ... The coming x86 refcount protection needs to be able to add trailing instructions to the GEN_*_RMWcc() operations. This extracts the difference between the goto/non-goto cases so the helper macros can be defined outside the #ifdef cases. Additionally adds argument naming to the resulting asm for referencing from suffixed instructions, and adds clobbers for "cc", and "cx" to let suffixes use _ASM_CX, and retain any set flags.
