The new symbol variants `:secrel_lo12:` and `:secrel_hi12:` aren't something that is in use anywhere else, but they seem to be a straightforward enough match to existing concepts.

This adds a new flag VK_SECREL in AArch64MCExpr, but to have this flag fall under the VK_SymLocBits bit mask, I had to make the mask VK_SymLocBits non-contiguous, to avoid having to renumber the rest of the enum.
