David Chase ad8447bed9 cmd/compile: fix late call expansion for SSA-able aggregate results and arguments
This change incorporates the decision that it should be possible to
run call expansion relatively late in the optimization chain, so that
(1) calls themselves can be exposed to useful optimizations
(2) the effect of selectors on aggregates is seen at the rewrite,
    so that assignment of parts into registers is less complicated
    (at least I hope it works that way).

That means that selectors feeding into SelectN need to be processed,
and Make* feeding into call parameters need to be processed.

This does however require that call expansion run before decompose
builtins.

This doesn't yet handle rewrites of strings, slices, interfaces,
and complex numbers.

Passes run.bash and race.bash
