[Bug debug/43516] [4.5 Regression] "-fcompare-debug failure" at -O2

We call get_alias_set on a 1 bit precision unsigned type with no alias set.
This calls lang_hooks.get_alias_set, which does c_common_signed_type.  With -g
it returns a type with alias set computed, but with -g0 that type doesn't have
alias set computed yet and a new alias set is created for it.
