[21/77] Replace SCALAR_INT_MODE_P checks with is_a <scalar_int_mode>
This patch replaces checks of "SCALAR_INT_MODE_P (...)" with "is_a <scalar_int_mode> (..., &var)" in cases where it becomes useful to refer to the mode as a scalar_int_mode. It also replaces some checks for the two constituent classes (MODE_INT and MODE_PARTIAL_INT). The patch also introduces is_a <scalar_int_mode> checks for some uses of HWI_COMPUTABLE_MODE_P, which is a subcondition of SCALAR_INT_MODE_P. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * wide-int.h (int_traits<unsigned char>) New class.
