Instead of possibly looping over the closure function parameter names
array multiple times, just do it once. Check each entry against the
provided argument names. If none match, check the required bit (if in
null-safe mode). Also keep a count of matched names to check that all
provided names matched after the iteration.
Now that optional name checking is part of the fragment built by
BuildClosureCallArgumentsValidCheck, that method builds checks for
exactly the same things as its namesake in Function.
Also refactor the variables used by the checker into read/write ones
that need to be allocated in the parsed function and read-only ones
that can just be temporaries since no Phi nodes are needed.
