The `if (ElementType)` condition only push back stride when base is not
pointer. I'm now allowing one dimension size to be unknown (pointer as base)
and sema has analysis to check if more than one indirection as base. My last
codegen test case is for testing pointer as base.

I don't think I understand this one. Why do you remove SizeV in the if
condition?

Doing this I'll get assertion error in this exact line if on a 32-bits target.

Do you mean I should set the type of Offset to Expr*?
