PR82045: Avoid passing machine modes through "..."

PR82045 is about a bootstrap failure on sparc-sun-solaris2.11.
The problem was that we were passing the new machine_mode wrapper
classes through "..."  to emit_library_call(_value), which then
read them back as ints instead.

The simplest fix seemed to be replace "..." with an array of
rtx_mode_ts, then provide wrappers for the common cases.  This
bulks out rtl.h a bit, but it does make things a bit more typesafe.
