[PATCH] D43457: [Evaluator] Improve evaluation of load/store

[Eugene Leviant via Phabricator via llvm-commits]

Unfortunately `ConstantFoldLoadFromConstPtr` seems to be useful, because it checks for GV initializer being constant and we're not forced by this constraint when evaluating static ctors.
However it turned out we can use `ConstantFoldLoadThroughBitcast` when evaluating both load and store.
