  ARM: Mark more generic libgcc functions as available

Generic libgcc/compiler-rt functions coexist with aeabi variants
(e.g., __divsi3  and __aeabi_idiv) according to my reading of the
build. At least in compiler-rt, they are aliases (such that I'm not sure
what the point of ever emitting the __aeabi name is).

They were previously removed from the available set on AEABI+AAPCS targets
to force selection of the preferred __aeabi_* variants, back when
only one implementation per libcall could be recorded.

Now that multiple implementations can be available per libcall, stop hiding
the generics and select the __aeabi_* variant explicitly as the preferred
implemntation. This reduces the number of special cases to consider for
future libcalls info improvements.
