runtime: rename _m_ to mp [generated]

_g_, _p_, and _m_ are primarily vestiges of the C version of the
runtime, while today we prefer Go-style variable names (generally gp,
pp, and mp).

This change replaces all remaining uses of _m_ with mp. There are very
few remaining and all replacements are trivial.

[git-generate]
cd src/runtime

rf 'mv canpanic._m_ canpanic.mp'
GOOS=solaris \
  rf 'mv semasleep._m_ semasleep.mp'
GOOS=aix GOARCH=ppc64 \
  rf 'mv semasleep._m_ semasleep.mp'
