cmd/compile: make clobber variadic

There are often many values to clobber.
Allow passing them all in at once.
The goal is increased rule readability.
As a bonus, it shrinks cmd/compile by ~97k, almost half a percent.
Package SSA requires 1.2% less memory to compile.

The single-line changes were make via regex,
and the remaining multi-line clobbers were manually combined.

Passes toolstash-check -all.
