x86/alternatives: Add macro comments
... so that when one stares at the .s output, one can find her way
around the resulting asm magic.
With it, ALTERNATIVE looks like this now:
# ALT: oldnstr
661:
...
662:
# ALT: padding
.skip ...
663:
.pushsection .altinstructions,"a"
...
.popsection
.pushsection .altinstr_replacement, "ax"
# ALT: replacement 1
6641:
...
6651:
.popsection
Merge __OLDINSTR() into OLDINSTR(), while at it.
No functional changes.
