Daniel Sanders fb9b99b26e [globalisel][combines] Don't sink G_TRUNC down to use if that use is a G_PHI 
This fixes a problem where the register allocator fails to eliminate a PHI
because there's a non-PHI in the middle of the PHI instructions at the start
of a BB.

This G_TRUNC can be better placed but this at least fixes the correctness issue
quickly. I'll follow up with a patch to the verifier to catch this kind of bug
in future.
