[Committed as obvious.]

DWARF DIEs do not contain DW_TAG_restrict_type when DWARF version is 2. CTF/BTF
generation feeds off DWARF DIEs, and as such, CTF records of kind
CTF_K_RESTRICT cease to be generated when DWARF version is 2.

This patch fixes the failure of these testcases on Darwin by using an explicit
-gdwarf-4 in the dg-options. This keeps the CTF record generation for restrict
type qualifier tested.
