Allow DW_OP_rot, DW_OP_neg, and DW_OP_abs in DIExpression (#160757)
The Ada front end can emit somewhat complicated DWARF expressions for
the offset of a field. While working in this area I found that I needed
DW_OP_rot (to implement a branch-free computation -- it looked more
difficult to add support for branching); and DW_OP_neg and DW_OP_abs
(just basic functionality).
