◆ addExclusiveRegPair()

static |
ARM's ldrexd/strexd take a consecutive register pair (represented as a single GPRPair register), Thumb's take two separate registers so we need to extract the subregs from the pair.

◆ GetDSubRegs()

GetDSubRegs - Get 4 D subregisters of a Q, QQ, or QQQQ register, corresponding to the specified register spacing.
Not all of the results are necessarily valid, e.g., a Q register only has 2 D subregisters.
