When actually emitting dwarf2, this now produces proper results.
When emitting ia64 unwind info, this removes a hard-coded assumption.

Not that there's much rtl to emit, since the CALL instruction
interpreting the procedure entry mask does almost all the work.
However, it means we're no longer emitting dwarf2 via the
text-based entry points.

        * config/vax/vax.md (define_c_enum unspecv): New.  Define the
        VUNSPEC_* constants here instead of via define_constants.

        (procedure_entry_mask): New insn.
        (prologue): New expander.
        * config/vax/vax.c (vax_add_reg_cfa_offset): New.
