[ELF] Add basic support for PPC LE
This patch adds changes to start supporting the Power 64-Bit ELF V2 ABI. This includes: - Changing the ElfSym::GlobalOffsetTable to be named .TOC. - Creating a GotHeader so the first entry in the .got is .TOC. - Setting the e_flags to be 1 for ELF V1 and 2 for ELF V2 Differential Revision: https://reviews.llvm.org/D44483 llvm-svn: 327871
