[OpenMP][OMPIRBuilder] Add Directives (master and critical) to OMPBuilder. Add support for Master and Critical directive in the OMPIRBuilder. Both make use of a new common interface for emitting inlined OMP regions called `emitInlinedRegion` which was added in this patch as well. Also this patch modifies clang to use the new directives when `-fopenmp-enable-irbuilder` commandline option is passed. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D72304

[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

[CodeGen] Emit a call instruction instead of an invoke if the called llvm function is marked nounwind This fixes cases where an invoke is emitted, despite the called llvm function being marked nounwind, because ConstructAttributeList failed to add the attribute to the attribute list. llvm optimization passes turn invokes into calls and optimize away the exception handling code, but it's better to avoid emitting the code in the front-end if the called function is known not to raise an exception.

[OpenMP][OMPIRBuilder] Add Directives (master and critical) to OMPBuilder. Add support for Master and Critical directive in the OMPIRBuilder. Both make use of a new common interface for emitting inlined OMP regions called `emitInlinedRegion` which was added in this patch as well. Also this patch modifies clang to use the new directives when `-fopenmp-enable-irbuilder` commandline option is passed. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D72304

[OPENMP] Improved code for generating debug info + generation of all OpenMP regions in termination scope Patch adds proper generation of debug info for all OpenMP regions. Also, all OpenMP regions are generated in a termination scope, because standard does not allow to throw exceptions out of structured blocks, associated with the OpenMP regions Differential Revision: http://reviews.llvm.org/D7935 llvm-svn: 231757

DebugInfo: Metadata constructs now start with DI* LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week. This commit was generated using the rename-md-di-nodes.sh upgrade script attached to PR23080, followed by running clang-format-diff.py on the `lib/` portion of the patch. llvm-svn: 236121

[OPENMP] Codegen for 'omp critical' directive. This patch adds codegen for constructs: #pragma omp critical [name] <body> It generates global variable ".gomp_critical_user_[name].var" of type int32[8]. Then it generates library call "kmpc_critical(loc, gtid, .gomp_critical_user_[name].var)", code for <body> statement and final call "kmpc_end_critical(loc, gtid, .gomp_critical_user_[name].var)".
