This is generally more readable due to the way the assembler aliases
work.
(This causes a lot of test changes, but it's not really as scary as it
looks at first glance; it's just mechanically changing a bunch of checks
for orr to check for mov instead.)

branches
Looping over all terminators exposed AArch64 tests hitting
an assert from analyzeBranch failing. I believe these cases
were miscompiled before.
e.g.
fcmp s0, s1
b.ne LBB0_1
b.vc LBB0_2
b LBB0_2
LBB0_1:
; Large block
LBB0_2:
; ...
Both of the individual conditional branches need to
be expanded, since neither can reach the final block.
Split the original block into ones which analyzeBranch
will be able to understand.

The branch relaxation pass has the worst test coverage
of any pass in AArch64. Add a few tests that hit some
large pieces of code in the pass.
