Dan Gohman dc884a7830 Generalize the zext(trunc(t) & C) instcombine to work even with
C is not a low-bits mask, and add a similar instcombine for
zext((trunc(t) & C) ^ C).

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
