Sanjay Patel c26502f012 [InstCombine] fix demanded-bits propagation for zext/trunc ...

I was comparing the demanded-bits implementations between InstCombine
and TargetLowering as part of investigating questions in D42088 and
noticed that this was wrong in IR. We were losing all of the prior
known bits when we got back to the 'zext'.
