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.

Sergi Mateo Bellido	31df1adbe9	[OpenMP] Adding support to the mutexinoutset dep-type ... Summary: this commit adds support to a new dependence type introduced in OpenMP 5.0. The LLVM OpenMP RTL already supports this feature, so we only need to modify CLANG to take advantage of them.

Kelvin Li	ad9ecbab42	[OpenMP] Allow negative lower bound in array sections based on pointers ... OpenMP 4.5 removed the restriction that array section lower bound must be non negative. This change is to allow negative values for array section based on pointers. For array section based on array type there is still a restriction: "The array section must be a subset of the original array." Patch by David S.
