Previously, ELFReader takes three template arguments: EFLT, LinkingContextT and FileT. FileT is itself templated. So it was a bit complicated. Maybe too much. Most architectures don't actually need to be parameterized for ELFT. For example, x86 is always ELF32LE and x86-64 is ELF64LE. However, because ELFReader requires a ELFT argument, we needed to parameterize a class even if not needed. This patch removes the parameter from the class. So now we can de-templatize such classes (I didn't do that in this patch, though). This patch also removes ContextT parameter since it didn't have to be passed as a template argument. llvm-svn: 234853
