Sema: fix generic fn instantiation with anytype
When the anytype parameter had only one-possible-value
(e.g. `void`), it would create a mismatch in the function type and the
function call. Now the function type and the callsite both omit the
one-possible-value anytype parameter in instantiated generic functions.3 files changed, 9 insertions(+), 2 deletions(-)
