cmd/gc: eliminate dead code in switch statements
Ordinary switch statements are rewritten

Staticly dead cases were not being eliminated
because the rewrite introduced a temporary,
which hid the fact that the case was a constant.
Stop doing that.
This eliminates dead code in the standard library at:
