New Revision: 234978

URL: http://llvm.org/viewvc/llvm-project?rev=234978&view=rev
Log:
[OPENMP] Codegen for 'firstprivate' clause in 'for' directive.

Adds proper codegen for 'firstprivate' clause in for directive. Initially codegen for 'firstprivate' clause was implemented for 'parallel' directive only.
Also this patch emits sync point only after initialization of firstprivate variables, not all private variables. This sync point is not required for privates, lastprivates etc., only for initialization of firstprivate variables.
