Use DW_OP_stack_value when reconstructing variable values with arithmetic.

When the location description of a source variable involves arithmetic
on the value itself, it needs to be marked with DW_OP_stack_value since it
is not describing the variable's location, but rather its value.

This is a follow-up to r297971 and fixes the source testcase quoted in
the comment in debuginfo-dce.ll.
