[OPENMP] Fix PR34925: Fix getting thread_id lvalue for inlined regions in C. If we try to get the lvalue for thread_id variables in inlined regions, we did not use the correct version of function. Fixed this bug by adding overrided version of the function getThreadIDVariableLValue for inlined regions. llvm-svn: 315578

[OPENMP]Provide correct data sharing attributes for loop control variables. Loop control variables are private in loop-based constructs and we shall take this into account when generate the code for inner constructs. Currently, those variables are reported as shared in many cases. Moved the analysis of the data-sharing attributes of the loop control variable to an early semantic stage to correctly handle their attributes. llvm-svn: 366474
