Alexey Bataev 7a54d76fa5 [OPENMP5.0]Allow teams directive outside of the target directives.
According to OpenMP 5.0, teams directives are allowed not only in the
target context, but also in the implicit parallel regions.

Alexey Bataev c2c21ef9d2 [OPENMP]Initial fix PR42392: Improve -Wuninitialized warnings for OpenMP programs.
Summary:
Some OpenMP clauses rely on the values of the variables. If the variable
is not initialized and used in OpenMP clauses that depend on the
variables values, it should be reported that the uninitialized variable
is used in the OpenMP clause expression.
This patch adds initial processing for uninitialized variables in OpenMP
constructs. Currently, it checks for use of the uninitialized variables
in the structured blocks.

Alexey Bataev 41ebe0ce64 [OPENMP]Fix PR41768: check DSA for globals with default(none) clauses.
If the default(none) was specified for the construct, we might miss
diagnostic for the globals without explicitly specified data-sharing
attributes. Patch fixes this problem.

Roman Lebedev a8f8d3b01e Revert "[OPENMP]Fix PR41768: check DSA for globals with `default(none)` clauses."
This has introduced (exposed?) a crash in clang sema,
that does not happen without this patch.
I'll followup in the original bugreport and commit with reproducer.

This reverts commit r360061.

only.

simd-based constructs without emission of OpenMP runtime calls.

Alexey Bataev db39021cee [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).
