CodeGen: Emit string literal in constant address space Some targets have constant address space (e.g. amdgcn). For them string literal should be emitted in constant address space then casted to default address space. Differential Revision: https://reviews.llvm.org/D46643 llvm-svn: 332279

CGDecl::emitStoresForConstant fix synthesized constant's name Summary: The name of the synthesized constants for constant initialization was using mangling for statics, which isn't generally correct and (in a yet-uncommitted patch) causes the mangler to assert out because the static ends up trying to mangle function parameters and this makes no sense. Instead, mangle to `"__const." + FunctionName + "." + DeclName`. Reviewers: rjmccall Subscribers: dexonsmith, cfe-commits Differential Revision: https://reviews.llvm.org/D54055 llvm-svn: 346915
