Jakub Kuderski d42deae8d8 There is a trunc(lshr (zext A), Cst) optimization in InstCombineCasts that ...

removes cast by performing the lshr on smaller types. However, currently there
is no trunc(lshr (sext A), Cst) variant.
This patch add such optimization by transforming trunc(lshr (sext A), Cst)
to ashr A, Cst.
