Eli Friedman 39d15bed50 [InstCombine] Don't widen metadata on store-to-load forwarding 
The original check for load CSE or store-to-load forwarding is wrong
when the forwarded stored value happened to be a load.

Ref https://github.com/JuliaLang/julia/issues/16894

Differential Revision: http://reviews.llvm.org/D21271
