Simon Pilgrim 652fd662fd [DAG] reduceBuildVecExtToExtBuildVec - don't combine if it would break a splat. ... reduceBuildVecExtToExtBuildVec was breaking a splat(zext(x)) pattern into buildvector(x, 0, x, 0, ..) resulting in much more complex insert+shuffle codegen. We already go to some lengths to avoid this in SimplifyDemandedVectorElts etc. when we encounter splat buildvectors. It should be OK to fold all splat(aext(x)) patterns - we might need to tighten this if we find a case where we mustn't introduce a buildvector(x, undef, x, undef, ..) but I can't find one. Fixes PR46461.		2020-06-27 11:03:57 +01:00
