[PATCH] [AArch64] Keep flags on the condition when instantiating a CB branch.

[Tim Northover]

Interesting point on the general principle; I'll have to bear it in mind in future. A common case is expanding a single instruction to multiple ones, where you often need to use different flags on the same register throughout the process.

Either way, this patch looks obvious. Go for it!

Tim.
