Martin Storsjö a92bacb796 [AArch64] [Windows] Properly add :lo12: reloc specifiers when generating assembly
This makes sure that assembly output actually can be assembled.

Set the correct MCExpr relocations specifier VK_PAGEOFF - and also
set VK_PAGE consistently even though it's not visible in the assembly
output.
