eac90446 - [clang][bytecode] Don't check instance pointers for mutability (#205820)

[clang][bytecode] Don't check instance pointers for mutability (#205820) The instance pointer being mutable is perfectly fine, we just can't read anything from it. This regresses a test case in `cxx11.cpp` where we now diagnose an extra frame for `U(g1.u)`, but this seems correct since the read is happening in the copy constructor of `U`.
