strub: handle volatile promoted args in internal strub [PR112938]

When generating code for an internal strub wrapper, don't clear the
DECL_NOT_GIMPLE_REG_P flag of volatile args, and gimplify them both
before and after any conversion.

While at that, move variable TMP into narrower scopes so that it's
more trivial to track where ARG lives.
