Fangrui Song 5d5f16204f Move PowerPC-specific MCSymbolRefExpr::VariantKind to PPCMCExpr ...

Most changes are mechanic, except:

* ELFObjectWriter::shouldRelocateWithSymbol: .TOC.@tocbase does not
  register the undefined symbol.  Move the handling into the
  Sym->isUndefined() code path.
* ELFObjectWriter::fixSymbolsInTLSFixups's VK_PPC* cases are moved to
  PPCELFObjectWriter::getRelocType. We should do similar refactoring
  for other targets and eventually remove fixSymbolsInTLSFixups.

In the future, we should classify PPCMCExpr similar to AArch64MCExpr.
