Hide regs_invalidated_by_call etc.
The previous patches removed all target-independent uses of
regs_invalidated_by_call, call_used_or_fixed_regs and
call_used_or_fixed_reg_p. This patch therefore restricts
them to target-specific code (and reginfo.c, which sets them up).

gcc/
* hard-reg-set.h (regs_invalidated_by_call): Only define if
IN_TARGET_CODE.
(call_used_or_fixed_regs): Likewise.
(call_used_or_fixed_reg_p): Likewise.
* reginfo.c (regs_invalidated_by_call): New macro.
