'thread backtrace'     => Control-C b (gud-bt)     "Show stack for the current thread."
'thread backtrace all' => Control-C B (gud-bt-all) "Show stacks for all the threads."

Change the function name of one existing shortcut:

'breakpoint list"      => Control-C l (gud-listb)  "List all breakpoints."

aliases installed and working.  They now work when the
matched pattern and the result instruction have exactly
the same operand list.

This is now enough for us to define proper aliases for
movzx and movsx, implementing rdar://8017633 and PR7459.

Note that we do not accept instructions like:
  movzx 0(%rsp), %rsi

GAS accepts this instruction, but it doesn't make any
sense because we don't know the size of the memory
operand.  It could be 8/16/32 bits.
