Daniel Hoekwater 0982d96186 [CodeGen][AArch64] Don't split inline asm goto blocks or their targets ...

Machine function splitting + branch relaxation currently don't properly
handle inline asm goto blocks that conditional branch to cold goto
labels. While such inline asm is technically invalid, machine
function splitting is the only thing that exposes it as such.

Since machine function splitting doesn't help too much in these
circumstances anyway, disable it for asm goto blocks and their targets.
