Log:
[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.
