genmodes: Define NUM_MODE_* macros
I was working on a patch that needed to calculate the number of
modes in a particular class. It seemed better to have genmodes
generate this directly rather than do the kind of dance that
expmed.h had.
gcc/
* genmodes.c (emit_insn_modes_h): Define NUM_MODE_* macros.
* expmed.h (NUM_MODE_INT): Delete in favor of genmodes definitions.
(NUM_MODE_PARTIAL_INT, NUM_MODE_VECTOR_INT): Likewise.
* real.h (real_format_for_mode): Use NUM_MODE_FLOAT and
NUM_MODE_DECIMAL_FLOAT.
(REAL_MODE_FORMAT): Likewise.
