Helper for {@link #assignAddressesAndFixBranches}, which checks the branch target size
requirement of each branch instruction to make sure it fits. For instructions that don't fit,
this rewrites them to use a {@code goto} of some sort. In the case of a conditional branch that
doesn't fit, the sense of the test is reversed in order to branch around a {@code goto} to the
original target.
