Resolve type of an array's element to be printed in case it is dynamic.
Otherwise we don't use the correct boundaries nor the right location.
Before:
ptype fivearr(1)
type = Type five
Type one
integer(kind=4) :: ivla(34196784:34196832,34197072:34197120,34197360:34197408)
End Type one :: tone
End Type five
After:
ptype fivearr(1)
type = Type five
Type one
integer(kind=4) :: ivla(2,4,6)
End Type one :: tone
End Type five

* gdb.fortran/vla-type.f90: Add test for static and dynamic arrays
of dynamic types.
