Jakub Jelinek 91c771ec8a openmp - Fix up && and || reductions [PR94366] 
As the testcase shows, the special treatment of && and || reduction combiners
where we expand them as omp_out = (omp_out != 0) && (omp_in != 0) (or with ||)
is not needed just for &&/|| on floating point or complex types, but for all
&&/|| reductions - when expanded as omp_out = omp_out && omp_in (not in C but
GENERIC) it is actually gimplified into NOP_EXPRs to bool from both operands,
which turns non-zero values multiple of 2 into 0 rather than 1.

This patch just treats all &&/|| the same and furthermore uses bool type
instead of int for the comparisons.

2021-07-01  Jakub Jelinek  <jakub@redhat.com>

	PR middle-end/94366
gcc/
	* omp-low.c (lower_rec_input_clauses): Rename is_fp_and_or to
	is_truth_op, set it for TRUTH_*IF_EXPR regardless of new_var's type,
	use boolean_type_node instead of integer_type_node as NE_EXPR type.
	(lower_reduction_clauses): Likewise.
libgomp/
	* testsuite/libgomp.c-c++-common/pr94366.c: New test.
