In D115311 <https://reviews.llvm.org/D115311>, we're looking to modify clang to emit i constraints rather
than X constraints for callbr's indirect destinations. Prior to doing
so, update all of the existing tests in llvm/ to match.

[clang][CGStmt] emit i constraint rather than X for asm goto indirect dests

As suggested in:
https://reviews.llvm.org/D114895#3177794
this will help simplify SelectionDAGISEL.

[SelectionDAGBuilder] drop special handling for CallBr

Now that indirect destinations are using "i" constraints rather than "X"
we no longer need this special handling.

Add a test case that was previously ICE'ing.
