[dev.regabi] cmd/compile: added limited //go:registerparams pragma for new ABI dev
This only works for functions; if you try it with a method, it will
fail. It does work for both local package and imports. For now,
it tells you when it thinks it sees either a declaration or a call of
such a function (this will normally be silent since no existing
code uses this pragma).
Note: it appears to be really darn hard to figure out if this
pragma was set for a method, and the method's call site. Better
ir.Node wranglers than I might be able to make headway, but it
seemed unnecessary for this experiment.
