The standard solution here is that rather than having 0x0013f318 as the
target address, you do something like this:

load register,=x'90836388'
xor register,=x'90909090'
(code to branch to where that register now points)

Or declare the target address as x'9013f318' and 'xor immediate' a x'90'
into the first byte... or other similar scheme...
