Compiler wants to know:

1. If a symbol will be referenced locally within the file. If a readonly
symbol with initializer is referenced with the file, compiler may
replace symbol read with its initializer. PRs 35402/35494/35501.
2. If a symbol will be referenced locally within the module, an optimized
relocation may be used, depend on symbol types. But for weak, undefined,
hidden function symbol, it is necessary to treat it as global for read.
PR 32219.
3. If a function will be called with in the module, an optimized
relocation may be used.

However, the current targetm.binds_local_p doesn't distinguish those
different usages. As the result, gcc makes wrong conclusions in some
cases, PR 32219.

I think targetm.binds_local_p should take a parameter to indicate
its usage.
