This is an idea on how to fix the https://reviews.llvm.org/D46103 problem with VerdefIndex.

By having Global symbol type we can avoid having unused PltIndex, GotPltIndex and DynsymIndex in each local symbol. VerdefIndex could be moved there too.

This reduces peak allocation when linking chrome from 568.1 to 562.1.
