[Patch]: Remove dead-code in gas for vax-vms

[Patch]: Remove dead-code in gas for vax-vms

[Tristan Gingold]

Hi,

there is some code between #ifdef OBJ_VMS/#endif in common gas code that may have been used for vax-vms.
But this platform is unsupported, so we may clean that up.

Ok for trunk ?

Yes, and no need to ask.  Commit as obvious.
