As suggested by Richard Biener in the comments of PR middle-end/102029,
the new test "INTEGRAL_TYPE_P (type) && !POINTER_TYPE_P (type) ..." is
redundant, and just "INTEGRAL_TYPE_P (type)" is the preferred form.
Committed as obvious/pre-approved, after a "make bootstrap" and
"make -k check" with no new failures on x86_64-pc-linux-gnu.
