[OpenMP] OpenMP 5.1 "assume" directive parsing support (#92731)
This is a minimal patch to support parsing for "omp assume" directives.
These are meant to be hints to a compiler's optimisers: as such, it is
legitimate (if not very useful) to ignore them. The patch builds on top
of the existing support for "omp assumes" directives (note spelling!).

Unlike the "omp [begin/end] assumes" directives, "omp assume" is
associated with a compound statement, i.e. it can appear within a
function. The "holds" assumption could (theoretically) be mapped onto
the existing builtin "__builtin_assume", though the latter applies to a
single point in the program, and the former to a range (i.e. the whole
of the associated compound statement).

This patch fixes sollve's OpenMP 5.1 "omp assume"-based tests.

[Frontend] Add leaf constructs and association to OpenMP/ACC directives (#83625)
Add members "leafConstructs" and "association" to .td describing
OpenMP/ACC directives. The naming follows the terminology used in the
OpenMP standard: a "leaf" construct is a construct that is itself not a
composition or a combination of other constructs, and "association" is
the source language construct to which the directive applies (e.g. loop,
block, etc.)

The tblgen-generated output then contains two additional functions
- getLeafConstructs(D), and
- getDirectiveAssociation(D)
plus "enum class Association", all in namespaces "llvm::omp" and
"llvm::acc".

Note: getLeafConstructs returns an empty sequence for a construct that
is itself a leaf construct.

Use the new functions to simplify a few OpenMP-related functions in
clang.

08bbff4aad [OpenMP] Codegen support for thread_limit on target directive for host
offloading

- This patch adds support for thread_limit clause on target directive according to OpenMP 51 [2.14.5]
- The idea is to create an outer task for target region, when there is a thread_limit clause, and manipulate the thread_limit of task instead. This way, thread_limit will be applied to all the relevant constructs enclosed by the target region.

eb61bde829 [OpenMP][CodeGen] Add codegen for combined 'loop' directives.
The loop directive is a descriptive construct which allows the compiler
flexibility in how it generates code for the directive's associated
loop(s). See OpenMP specification 5.2 [257:8-9].

Codegen added in this patch for the combined 'loop' directives are:

'target teams loop'     -> 'target teams distribute parallel for'
'teams loop'            -> 'teams distribute parallel for'
'target parallel loop'  -> 'target parallel for'
'parallel loop'         -> 'parallel for'

NOTE: The implementation of the 'loop' directive itself is unchanged.

Runtime support already exists in LLVM OpenMP runtime (see

The value used to identify an inoutset dependency type in the LLVM
OpenMP runtime is 8.

Some tests updated due to change in dependency type error messages that
now include new dependency type. Also updated

A new function, getBestWhenMatchForContext, is defined in llvm/Frontend/OpenMP/OMPContext.h

Currently this function return the index of the when clause with the highest score from the ones applicable in the Context.
But this function is declared with an array which can be used in OpenMP 5.1 implementation to select all the valid when clauses which can be resolved in runtime. Currently this array is set to null by default and its implementation is left for future.
