Support for parsing the externally_visible attribute was added in b7e44f4.

It needs to be properly handled.

See the GCC documentation about the attribute.

This attribute is applied in the ISR macro for AVR. While externally_visible is unhandled, ISRs can have their visibility changed during optimization.

Once this is done, it can be upstreamed (see LLVM bug 16683).
