Matthew Dempsky 6da1661371 [dev.typeparams] cmd/compile: simplify inlining variadic calls
We already have and use FixVariadicCall to normalize non-dotted calls
to variadic functions elsewhere in the compiler to simplify rewriting
of function calls. This CL updates inl.go to use it too.

A couple tests need to be updated to (correctly) expect diagnostics
about "... argument" instead of a slice literal. This is because
inl.go previously failed to set Implicit on the slice literal node.
