P2 is the right setting for this bug; it's popping up often enough to make it
worth fixing.  Disabling the inlining in the case that the argument type
doesn't match (closely enough) the parameter type seems reasonable to me, even
without introducing a subsequent runtime abort.  That would be equivalent to
the behavior if the function called appeared in a different translation unit.

The failures in 3.4 and later are in fold_const, so the gen_lowpart problem is
now avoided by, well, ICEing earlier :)

A backport of the patch bootstraps & regtests ok on the 4.1 branch, but I'm
unsure we want the side-effects of the rejects-valid, because this is valid
code according to jsm (only undefined at runtime).
