[delayed-symfile] [commit] Fix a regression on delayed retrievingof the unwinding debug info.

commit 6a37c2b9962258ecf9299cc34a650e64a06acaa5

There was a regression on gdb.base/savedregs.exp.

quick_addrmap/require_partial_symbols should be used even for the unwind debug
info checking as its load has been also delayed by this branch.

Disputable is whether the delayed reading of partial symtabs and unwind info
should not be split in half and read separately on their specific demand.
Assuming their current load together has been decided for the GDB code
simplicity and it has no real performance impact.
