Jonas Hahnfeld 071dca24ce [OpenMP] Require trivially copyable type for mapping
A trivially copyable type provides a trivial copy constructor and a trivial
copy assignment operator. This is enough for the runtime to memcpy the data
to the device. Additionally there must be no virtual functions or virtual
base classes and the destructor is guaranteed to be trivial, ie performs
no action.
The runtime does not require trivial default constructors because on alloc
the memory is undefined. Thus, weaken the warning to be only issued if the
mapped type is not trivially copyable.

Alexey Bataev bef93a98cd [OPENMP50]Treat range-based for as canonical loop.
According to OpenMP 5.0, range-based for is also considered as a
canonical form of loops.

Alexey Bataev 1be634044d [OPENMP] Update the diagnosis message for canonical loop form, by Chi
Chun Chen.

The previous patch (https://reviews.llvm.org/D54441) support the
relational-op != very well for openmp canonical loop form, however,
it didn't update the diagnosis message. So this patch is simply
update the diagnosis message by adding !=, update the test
related to it, and update the section number for canonical loop
form for OpenMP 5.0 in comment.

Kelvin Li efbe4afbda [OPENMP] Support relational-op != (not-equal) as one of the canonical
forms of random access iterator
    
In OpenMP 4.5, only 4 relational operators are supported: <, <=, >, 
and >=.  This work is to enable support for relational operator 
!= (not-equal) as one of the canonical forms.

Alexey Bataev f07946e101 [OPENMP]Fix PR39372: Does not complain about loop bound variable not
being shared.

According to the standard, the variables with unspecified data-sharing
attributes in presence of `default(none)` clause must be reported to
users. Compiler did not generate error reports for the variables used in
other OpenMP regions. Patch fixes this.

simd-based constructs without emission of OpenMP runtime calls.

Alexey Bataev b358f9922a [OPENMP] Do not allow variables to be first|last-privates in

Alexey Bataev 5372fb8cc1 [OPENMP] Fix for PR34398: assert with random access iterator if the
step>1.

If the loop is a loot with random access iterators and the iteration
construct is represented it += n, then the compiler crashed because of
reusing of the same MaterializedTemporaryExpr around N. Patch fixes it
by using the expression as written, without any special kind of
wrappings.

Diana Picus 8b44bbc077 Revert "[OpenMP] Sema and parsing for 'teams distribute simd’ pragma"
This reverts commit r279003 as it breaks some of our buildbots (e.g.
clang-cmake-aarch64-quick, clang-x86_64-linux-selfhost-modules).

The error is in OpenMP/teams_distribute_simd_ast_print.cpp:
