Arnold Schwaighofer ae9312c487 ISel: Fix FastISel of swifterror values ...

The code assumed that we process instructions in basic block order.  FastISel
processes instructions in reverse basic block order. We need to pre-assign
virtual registers before selecting otherwise we get def-use relationships wrong.

This only affects code with swifterror registers.
