Ulrich Weigand 68b292b026 [PowerPC] ELFv2 dynamic loader support ... This patch enables the new ELFv2 ABI in the runtime dynamic loader. The loader has to implement the following features: - In the ELFv2 ABI, do not look up a function descriptor in .opd, but instead use the local entry point when resolving a direct call. - Update the TOC restore code to use the new TOC slot linkage area offset. - Create PLT stubs appropriate for the ELFv2 ABI. Note that this patch also adds common-code changes. These are necessary because the loader must check the newly added ELF flags: the e_flags header bits encoding the ABI version, and the st_other symbol table entry bits encoding the local entry point offset. There is currently no way to access these, so I've added ObjectFile::getPlatformFlags and SymbolRef::getOther accessors.
