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). gdb/ChangeLog: * gdbarch.sh (gdbarch_num_cooked_regs): New. * gdbarch.h: Re-generate. * ax-gdb.c (gen_expr): Use gdbarch_num_cooked_regs. * dwarf2-frame.c (dwarf2_frame_cache): Likewise. * eval.c (evaluate_subexp_standard): Likewise. * findvar.c (value_of_register): Likewise.
