Subject: Fix for PR30639: CGDebugInfo Null dereference with OpenMP array
 access, by Erich Keane

OpenMP creates a variable array type with a a null size-expr. The Debug
generation failed to due to this. This patch corrects the openmp
implementation, updates the tests, and adds a new one for this
condition.
