[dev.ssa] cmd/compile: fix registers for in-place instructions
Some of these were right; others weren't.
Fixes 'GOGC=off GOSSAPKG=mime go test -a mime'.
The right long term fix is probably to teach the
register allocator about in-place instructions.
In the meantime, all the tests that we can run
now pass.
