x86, asm: define CC_SET() and CC_OUT() macros The CC_SET() and CC_OUT() macros can be used together to take advantage of the new __GCC_ASM_FLAG_OUTPUTS__ feature in gcc 6+ while remaining backwards compatible. CC_SET() generates a SET instruction on older compilers; CC_OUT() makes sure the output is received in the correct variable. Signed-off-by: H.
