Hide call_used_regs in target-independent code
Now that tests of call_used_regs go through call_used_or_fixed_reg_p,
we can hide call_used_regs from target-independent code. (It still
needs to be available to targets for the conditional register usage
hooks.)

gcc/
* hard-reg-set.h (call_used_regs): Only define if IN_TARGET_CODE.
(call_used_or_fixed_reg_p): Expand definition of call_used_regs.
* reginfo.c (call_used_regs): New macro.
