Bug noted in D112717 can be sidestepped with this change. Expanding all ConstantExpr involved with LDS up front makes the variable specialisation simpler. Excludes ConstantExpr that don't access LDS to avoid disturbing codegen elsewhere. Reviewed By: rampitec Differential Revision: https://reviews.llvm.org/D133422
