Fangrui Song e9262edf0d [ELF] SymbolTable:🔣 don't filter out PlaceholderKind 
Placeholders (-y and redirectSymbols removed versioned symbols) are very rare and
the check just makes symbol table iteration slower. Most iterations filter out
placeholders anyway, so this change just drops the filter behavior.

For "Add symbols to symtabs", we need to ensure that redirectSymbols sets
isUsedInRegularObj to false when making a symbol placeholder, to avoid an
assertion failure in SymbolTableSection<ELFT>::writeTo.

My .text is 2KiB smaller. The speed-up linking chrome is 0.x%.
