Currently, we call Warnl in SSA backend when we see a function
(defined or called) with regparams pragma. Calling Warnl in
concurrent environment is racy. As the debugging output is
temporary, for testing purposes we just pass -c=1. We'll remove
the pragma and the debugging print some time soon.

Now that TailCallStmt carries an *ir.Name instead of a *types.Sym,
callTargetLSym can be similarly updated to take the target function as
an *ir.Name.
This inches us closer towards being able to move Linksym and other
properties from *types.Sym to *ir.Name, where they belong.
Passes toolstash -cmp w/ -gcflags=all=-abiwrap.

The feature being tested is insensitive to the OS anyway.

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.
