Introduce gdbarch_num_cooked_regs
The expression
gdbarch_num_regs (gdbarch) + gdbarch_num_pseudo_regs (gdbarch)
is used quite often to find the number of cooked registers (raw + pseudo
registers). This patch introduces gdbarch_num_cooked_regs, which does
the equivalent. It substantially reduces required wrapping in some
places, so should improve readability.
There is a for loop in m68hc11_frame_unwind_cache that had iterated
until (the equivalent of) gdbarch_num_cooked_regs (gdbarch) - 1. During
review, we concluded that this is most likely an off-by-one mistake, so
I replaced it with gdbarch_num_cooked_regs (gdbarch).
