If the gain is for human readers of the API rather than the compiler and
some level of automated checking, what about this trick:

#define constp

Then you can use it wherever you want to instruct readers that the
parameter is a constant, it's now a noise word as far as the compiler is
concerned (thanks to the precompiler replacing it with an empty string).
