Some various improvements for inline asm code generation.

The "RFC" is really patches 4 and 5, they propose a more readable format
for alternatives and objtool annotations.  Bikeshedding welcome.

If a general format is agreed upon, we could do similar for other
annotations like WARN/BUG, static branches/calls, etc.

Josh Poimboeuf (5):
  objtool: Remove ANNOTATE_IGNORE_ALTERNATIVE from CLAC/STAC
  objtool, x86/hweight: Remove ANNOTATE_IGNORE_ALTERNATIVE
  noinstr: Use asm_inline() in instrumentation_{begin,end}()
  x86/alternative: Improve code generation readability
  objtool: Improve code generation readability
