For a -g0 -fasynchronous-unwind-tables exec (without .debug_info but with .eh_frame section), start using the dwarf2 unwinder instead of the "amd64 epilogue override" unwinder, by returning true in compunit_epilogue_unwind_valid for cust == nullptr. This has effect both on the amd64 and i386 targets, but only add amd64 test-case gdb.base/unwind-on-each-insn-amd64-2.exp.
