Rename signed integer 16/34-bit macros.
2019-12-20 Michael Meissner <meissner@linux.ibm.com>
* config/rs6000/predicates.md (cint34_operand): Use
SIGNED_INTEGER_34BIT_P macro.
* config/rs6000/rs6000.c (num_insns_constant_gpr): Use the
SIGNED_INTEGER_16BIT_P and SIGNED_INTEGER_34BIT_P macros.
(address_to_insn_form): Use the SIGNED_INTEGER_16BIT_P and
SIGNED_INTEGER_34BIT_P macros.
* config/rs6000/rs6000.h (SIGNED_INTEGER_NBIT_P): New macro.
(SIGNED_INTEGER_16BIT_P): Rename SIGNED_16BIT_OFFSET_P to be
SIGNED_INTEGER_34BIT_P.
(SIGNED_INTEGER_34BIT_P): Rename SIGNED_34BIT_OFFSET_P to be
SIGNED_INTEGER_34BIT_P.
