RuntimeLibcalls: Really move default libcall handling to tablegen (#148780)
Hack in the default setting so it's consistently generated like
the other cases. Maintain a list of targets where this applies.
The alternative would require new infrastructure to sort the system
library initialization in some way.

I wanted the unhandled target case to be treated as a fatal
error, but it turns out there's a hack in IRSymtab using
RuntimeLibcalls, which will fail out in many tests that
do not have a triple set. Many of the failures are simply
running llvm-as with no triple, which probably should not
depend on knowing an accurate set of calls.
