ARM: move some logic from processFixupValue to applyFixup. processFixupValue is called on every relaxation iteration. applyFixup is only called once at the very end. applyFixup is then the correct place to do last minute changes and value checks. While here, do proper range checks again for fixup_arm_thumb_bl. We used to do it, but dropped because of thumb2. We now do it again, but use the thumb2 range. llvm-svn: 306177

Slightly saner handling of thumb branches. The generic infrastructure already did a lot of work to decide if the fixup value is know or not. It doesn't make sense to reimplement a very basic case: same fragment. llvm-svn: 252090

// CHECK-NOT: error

Go back to producing relocations for out of range symbols. This brings back the behavior from before r252090 for out of range symbols. Should bring some arm bots back. llvm-svn: 252119
