[committed] VAX: Use `rtx_code' to hold the RTL expression code in `vax_rtx_costs'

[Maciej W. Rozycki]

Use `enum rtx_code' rather than `int' to hold the the RTL expression 
code in `vax_rtx_costs', matching the type these codes have been defined 
with and making debugging just a tiny little bit easier.

        gcc/
        * config/vax/vax.c (vax_rtx_costs): Use `rtx_code' rather than 
        `int' for `code'.

Hi,

 No regressions in `vax-netbsdelf' testing.  Committed as obvious.
