tree-optimization/97199 - fix virtual operand update in if-conversion

This fixes a corner case with virtual operand update in if-conversion
by re-organizing the code to remove edges only after the last point
we need virtual PHI operands to be available.

PR tree-optimization/97199
* tree-if-conv.c (combine_blocks): Remove edges only
after looking at virtual PHI args.
