Nico Weber 9721197520 [lld/mac] Set branchRange a bit more carefully 
- Don't subtract thunkSize from branchRange. Most places care about
  the actual maximal branch range. Subtract thunkSize in the one place
  that wants to leave room for a thunk.
- Set it to 0x800_0000 instead of 0xFF_FFFF
- Subtract 4 for the positive branch direction since it's a
  two's complement 24bit number sign-extended mutiplied by 4,
  so its range is -0x800_0000..+0x7FF_FFFC
- Make boundary checks include the boundary values

This doesn't make a huge difference in practice. It's preparation
for a "real" fix for PR51578 -- but it also lets the repro in comment 0
in that bug place one more thunk before hitting the TODO.
