Fix an issue in some Thumb fixups, where the effective PC address needs to be 4-byte aligned when calculating
the offset. Add a new fixup flag to represent this, and use it for the one fixups that I have a testcase for needing
this. It's quite likely that the other Thumb fixups will need this too, and to have their fixup encoding logic
adjusted accordingly.
