[PATCH] [AArch64] Implement pseudo LDR <reg>, =<literal/label>

[David Peixotto]

Minor cleanup, otherwise LGTM.

As a suggestion for the future I think it would be better to start a new differential revision for each patch. Also, if you add "Differential Revison: <url>" to the commit message it will close it automatically on commit.

----------------
use cast<> instead of dyn_cast<> when not checking the return value for null.
