[OPENMP] Fix for PR32333: Crash in call of outlined Function. If the type of the captured variable is a pointer(s) to variably modified type, this type was not processed correctly. Need to drill into the type, find the innermost variably modified array type and convert it to canonical parameter type. llvm-svn: 299868
