Benjamin Kramer c8a8544b79 InstCombine: Don't claim to be able to evaluate any shl in a zexted type.
The shift amount may be larger than the type leading to undefined behavior.
Limit the transform to constant shift amounts. While there update the bits to
clear in the result which may enable additional optimizations.
