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
