Alok Kumar Sharma 6077c65472 [DebugInfo] Upgrade DISubrange to support Fortran dynamic arrays
This patch upgrades DISubrange to support fortran requirements.

Summary:
Below are the updates/addition of fields.
lowerBound - Now accepts signed integer or DIVariable or DIExpression,
earlier it accepted only signed integer.
upperBound - This field is now added and accepts signed interger or
DIVariable or DIExpression.
stride - This field is now added and accepts signed interger or
DIVariable or DIExpression.
This is required to describe bounds of array which are known at runtime.

Testing:
unit test cases added (hand-written)
check clang
check llvm
check debug-info
