* Replace Sema-level implementation of -fassume-sane-operator-new with aRichard Smith2016-04-071-2/+2
| | | | | | | | | | | | | | CodeGen-level implementation. Instead of adding an attribute to clang's FunctionDecl, add the IR attribute directly. This means a module built with this flag is now compatible with code built without it and vice versa. This change also results in the 'noalias' attribute no longer being added to calls to operator new in the IR; it's now only added to the declaration. It also fixes a bug where we failed to add the attribute to the 'nothrow' versions (because we didn't implicitly declare them, there was no good time to inject a fake attribute). llvm-svn: 265728

This fixes a bug where CodeGen would sometimes try to emit an expression with the wrong type for the element being initialized.
