gdb: add value::allocate_register
Add value::allocate_register, to facilitate allocating a value
representing a register in a given frame (or rather, in the given
frame's previous frame). It will be used in a subsequent patch. I
changed one relatively obvious spot that could use it, to at least
exercise the code path.
