Updated status to 'done' for OpenMP 6.0 features:
- OpenMP directives in concurrent loop regions
- atomics constructs on concurrent loop regions
- Lift nesting restriction on concurrent loop
Removed duplicate OpenMP 6.0 feature per Michael Klemm:
- atomic constructs in loop region
Add initial parsing/sema support for new assumption clause so clause can
be specified. For now, it's ignored, just like the others.
Added support for 'no_openmp_construct' to release notes.
Testing
- Updated appropriate LIT tests.
- Testing: check-all
threadset clause is part of free-agent threads. But, free-agent threads
also involves runtime implementation. So, added an separate entry for
threadset clause and claimed it for clang.

The 'align' modifier is now accepted in the 'allocate' clause. Added LIT
tests covering codegen, PCH, template handling, and serialization for
'align' modifier.
Added support for align-modifier to release notes.
Testing
- New allocate modifier LIT tests.
- OpenMP LIT tests.
- check-all
This PR adds support seq_cst (sequential consistency) clause for the
flush directive in OpenMP. The seq_cst clause enforces a stricter memory
ordering, ensuring that all threads observe the memory effects of the
flush in the same order, improving consistency in memory operations
across threads.

By the OpenMP standard, `num_teams` clause can only accept one
expression (for now). In this patch, we extend it to allow to accept
multiple expressions when it is used with `target teams ompx_bare`
construct. This will allow to launch a multi-dim grid, same as CUDA/HIP.
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.
This is only for struct containing nested structs with user defined
mappers.
Add four functions:
1>buildImplicitMap: build map for default mapper
2>buildImplicitMapper: build default mapper.
3>hasUserDefinedMapper for given mapper name and mapper type, lookup
user defined map, if found one return true.
4>isImplicitMapperNeeded check if Mapper is needed
During create map, in checkMappableExpressionList, call
isImplicitMapperNeeded when it return true, call buildImplicitMapper to
generate implicit mapper and added to map clause.

Notifying assume directive as 'worked on'. When checked on slack
channel, nobody was working on assume directive.

In Clang's OpenMPSupport.rst, "extension" is currently overloaded to
describe both:
1. Standard OpenMP features that appear only in recent versions of the
OpenMP spec.
2. Non-standard features supported by Clang. This usage appears in
the final table on the page.
Last fall, we discussed this issue in the OpenMP in LLVM call and
agreed it should be corrected. This patch takes the simple approach
of dropping the word "extension" for all occurrences of the first
usage. The result seems to read well.
