x86/asm: Make objtool unreachable macros independent from GCC version
The ASM_UNREACHABLE macro isn't GCC version-specific, so move it outside
the GCC 4.5+ check. Otherwise the 0-day robot will report objtool
warnings for uses of ASM_UNREACHABLE with GCC 4.4.
Also move the annotate_unreachable() macro so the related macros can
stay together.
