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.

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.

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.

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).
