Jeff Trull 3b6df8adb1 Include __LINE__, __FILE__, __INCLUDE_LEVEL__, and __VA_OPT__ in hooks (#87) ...

* Run hooks for certain predefined object-like macros

These are the "dynamic" macros with their own special execution path.
Most predefined macros can be computed at startup time; those were
already covered by the normal expansion code.

*  __VA_OPT__ is supported as a function-like macro

It is referred to as such in the proposal. __VA_ARGS__ is not supported, under the theory that it represents a parameter or set of parameters, and no hooks are called for parameter substitutions.
