Subject: [PATCH 31/52] gas: revert moving of md_pseudo_table from const

The base system expect md_pseudo_table to be constant, Changing the
definition will break other architectures when compiled with a
unified source code.

Patch reverts the change away from const, and implements a newer
dynamic handler that passes the correct argument value based on word
size.
