Log Message

Add pretty-printer for MPX bnd registers.

Boundary length is simpler implemented by means of a pretty
printer. This simplifies users life when examining a bound register.

Changelog:
2013-11-20 Walfred Tedeschi <[e-mail]>

* python/lib/gdb/command/bound_register.py: New file.
* gdb/data-directory/Makefile.in: copy bond_register.py to the right path to
be initialized at gdb startup.
testsuite/
* gdb.python/py-pp-maint.exp: Consider new pretty-print added for registers.
