C/C++ permits to use || and && (logical OR and logical AND) for
floating-point and complex scalars; those evaluated unequal zero
and the result is of type 'int' with value 0 or 1.
While || and && with floating-point numbers is somewhat sensible,
it does not really make sense to use a non-bool/non-integer as
reduction variable – but as C/C++ permits this and OpenMP follows
the base language, this patch implements it.
OK for mainline?
Tobias
PS: The https://github.com/clang-ykt/omptests testsuite uses it
and this patch silences 1008 'error:' lines.

OpenMP: Support complex/float in && and || reduction
C/C++ permit logical AND and logical OR also with floating-point or complex
arguments by doing an unequal zero comparison; the result is an 'int' with
value one or zero. Hence, those are also permitted as reduction variable,
even though it is not the most sensible thing to do.
gcc/c/ChangeLog:
* c-typeck.c (c_finish_omp_clauses): Accept float + complex for || and &&
reductions.
gcc/cp/ChangeLog:
* semantics.c (finish_omp_reduction_clause): Accept float + complex for || and &&
reductions.
gcc/ChangeLog:
* omp-low.c (lower_rec_input_clauses, lower_reduction_clauses): Handle && and ||
with floating-point and complex arguments.
libgomp/ChangeLog:
* testsuite/libgomp.c-c++-common/reduction-1.c: New test.
* testsuite/libgomp.c-c++-common/reduction-2.c: New test.
* testsuite/libgomp.c-c++-common/reduction-3.c: New test.
