Jakub Kuderski 7cd4810021 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.
