This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

The codegen for simd constructs was affected by the presence (or
absence) of the 'monotonic' schedule modifier for worksharing
loops. The modifier is only intended to apply to the scheduling of
chunks for a thread, not iterations of a loop inside a chunk.
In addition, the monotonic modifier was applied to worksharing loops
by default if no schedule clause was present; the referenced part of
the OpenMP 4.5 spec in the code (section 2.7.1) only applies if the
user specified a schedule clause with a static kind but no modifier.
Without a user-specified schedule clause we should default to
nonmonotonic scheduling.

Summary:
According to OpenMP 5.0, nonmonotonic modifier can be used with all
schedule kinds, not only dynamic and guided as in OpenMP 4.5.

Instead of generating llvm.mem.parallel_loop_access metadata, generate
llvm.access.group on instructions and llvm.loop.parallel_accesses on
loops. There is one access group per generated loop.
This is clang part of D52116/r349725.

Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.
