Hello!

This change renames two @internal constraints to free two letters.

2014-06-01  Uros Bizjak  <ubizjak@gmail.com>

    * config/i386/constraints.md (Bw): Rename from 'w'.
    (Bz): Rename from 'z'.
    * config/i386/i386.md: Change 'w' to 'Bw' and 'z' to 'Bz' globally.

Tested on x86_64-linux-gnu {,-m32}  and committed to mainline.

Uros.
