[ELF] Move gotIndex/pltIndex/globalDynIndex to SymbolAux
to decrease sizeof(SymbolUnion) by 8 on ELF64 platforms.
Symbols needing such information are typically 1% or fewer (5134 out of 560520
when linking clang, 19898 out of 5550705 when linking chrome). Storing them
elsewhere can decrease memory usage and symbol initialization time.
There is a ~0.8% saving on max RSS when linking a large program.
Future direction:
* Move some of dynsymIndex/verdefIndex/versionId to SymbolAux
* Support mixed TLSDESC and TLS GD without increasing sizeof(SymbolUnion)
