Many glvalue expressions aren't of their respective reference type - they are simply glvalues of their value type. This was causing problems when we were trying to obtain type of the original expression while evaluating certain glvalue bit-casts. Fixed by artificially forging a reference type to provide to the casting procedure. Differential Revision: https://reviews.llvm.org/D46224 llvm-svn: 331558
