Sure it would. But what for do we have gdbarch_num_regs? I dont think its a good idea
to either use gdbarch_num_regs or ARRAY_SIZE(whatever) at will. This is redundant and error-prone.
Btw, there are two further uses of gdbarch_num_regs in that file.

For my opinion gdbarch should be used to describe an architecture.
