Change to recognize the need for a function table via symbols.

To manage the transitional period in which the compiler doesn't yet
produce TABLE_NUMBER relocations and doesn't residualize table symbols,
the linker will treat the case in which there are tables but no symbols
as being the "before" state.  In that case it will synthesize symbols
for the defined and imported tables.

Depends on D91849 <https://reviews.llvm.org/D91849>.
