Update template-id-expr.cpp test to work when compiler defaults to non-C++03 standard

[dyung]

Summary

Recently a change was made to this test in r294639 which fails because the compiler only generates one of the warnings when the compiler is in C++03 or lower mode.

This change fixes that as well as adds explicit run lines to run the test in C++03 and C++11 modes.
