runtime: copy some functions from math/bits to runtime/internal/sys CL 201765 activated calls from the runtime to functions in math/bits. When coverage and race detection were simultaneously enabled, this caused a crash when the covered+race-checked code in math/bits was called from the runtime before there was even a P. PS Win for gdlv in helping sort this out. TODO - next CL intrinsifies the new functions in runtime/internal/sys TODO/Would-be-nice - Ctz64 and TrailingZeros64 are the same function; 386.s is intrinsified; clean all that up. Fixes #35461. Updates #35112.
