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.

Alexey Bataev cbecfdfefe [OpenMP] Fix trailing space when printing pragmas, by Joel. E. Denny
Summary:
-ast-print prints omp pragmas with a trailing space.  While this
behavior is likely of little concern to most users, surely it's
unintentional, and it's annoying for some source-level work I'm
pursuing.  This patch focuses on omp pragmas, but it also fixes
init_seg and loop hint pragmas because they share implementation.

The testing strategy here is to add usually just one '{{$}}' per
relevant -ast-print test file.  This seems to achieve good code
coverage.  However, this strategy is probably easy to forget as the
tests evolve.  That's probably fine as this fix is far from critical.
The main goal of the testing is to aid the initial review.

This patch also adds a fixme for "#pragma unroll", which prints as
"#pragma unroll (enable)", which is invalid syntax.

Alexey Bataev a8a9153a37 [OPENMP] Support for -fopenmp-simd option with compilation of simd loops
only.

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

Alexey Bataev 2b86f21ce5 [OPENMP] Allow only loop control variables in distribute simd
directives.

According to the OpenMP standard, only loop control variables can be
used in linear clauses of distribute-based simd directives.

Serge Pavlov a67a4d2f3c Make output of -ast-print a valid C++ code.
Output generated by option -ast-print looks like C/C++ code, and it
really is for plain C. For C++ the produced output was not valid C++
code, but the differences were small. With this change the output
is fixed and can be compiled. Tests are changed so that output produced
by -ast-print is compiled again with the same flags and both outputs are
compared.

Option -ast-print is extensively used in clang tests but it itself
was tested poorly, existing tests only checked that compiler did not
crash. There are unit tests in file DeclPrinterTest.cpp, but they test
only terse output mode.

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:
