Add unit tests for functions in LLVMFrontendOpenACC. As notice in D91470 these functions were not tested
as well as the ones for OpenMP (D91643). This patch add tests for the OpenACC part.

As noticed in D91470, some of the functions of LLVMFrontend, are not tested within the library itself (but indirectly by its users clang and flang). In particular, the file OMP.cpp which is generated by tablegen was not tested at all.
Add tests for the parsing helpers in OMP.cpp. These are not meant to be exhaustive tests, just to ensure that we have some basic tests for all API functions.

9218ff50f9 removed the BUILD.txt file, and as a subtle side-effect
libLLVMFrontendOpenACC wasn't a dependency of `ninja check` anymore.
However llvm-config requires all components to be built, and the
relevant test is broken when libLLVMFrontendOpenACC isn't built.
Unittest for libLLVMFrontendOpenACC are pending, but this addition
should fix some bots in the meantime.
This is the first of multiple parts to make OpenMP context/trait
handling reusable and generic. This patch was originally part of D71830
but with the unit tests it can be tested independently.
This patch implements an almost complete handling of OpenMP
contexts/traits such that we can reuse most of the logic in Flang
through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP.
All but construct SIMD specifiers, e.g., inbranch, and the device ISA
selector are define in llvm/lib/Frontend/OpenMP/OMPKinds.def. From
these definitions we generate the enum classes TraitSet,
TraitSelector, and TraitProperty as well as conversion and helper
functions in llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}.
The OpenMP context is now an explicit object (see `struct OMPContext`).
This is in anticipation of construct traits that need to be tracked. The
OpenMP context, as well as the VariantMatchInfo, are basically made up
of a set of active or respectively required traits, e.g., 'host', and an
ordered container of constructs which allows duplication. Matching and
scoring is kept as generic as possible to allow easy extension in the
future.

This patch combines the `emitParallel` logic prototyped in D61953 with
the OpenMPIRBuilder (D69785) and introduces `CreateParallel`.

This is the initial patch for the OpenMP-IR-Builder, as discussed on the
mailing list ([1] and later) and at the US Dev Meeting'19.
The design is similar to D61953 but:
- in a non-WIP status, with proper documentation and working.
- using a OpenMPKinds.def file to manage lists of directives, runtime
functions, types, ..., similar to the current Clang implementation.
- restricted to handle only (simple) barriers, to implement most
`#pragma omp barrier` directives and most implicit barriers.
- properly hooked into Clang to be used if possible (D69922).
- compatible with the remaining code generation.
Parts have been extracted into D69853.
The plan is to have multiple people working on moving logic from Clang
here once the initial scaffolding (=this patch) landed.
