which is can be inaccurate. Instead, classify the declaration and emit
an appropriate diagnostic for the new declaration and an appropriate
note pointing to the old one.

- This is designed to make it obvious that %clang_cc1 is a "test variable"

can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
