Optimization in 2439c22ff6 introduced an array `absentArguments` with
default values of all parameter types, which is copied in `callBy`
instead of being recomputed each time. Unfortunately, its size was
computed incorrectly: `maskSize` should only take into account
value parameters (see the `parameter.kind == KParameter.Kind.VALUE`
check in `callBy`).
This led to an issue where if the function had 32 * N value parameters
and 1 receiver parameter, `maskSize` was greater by 1 than expected,
which caused an exception due to mismatching argument array sizes.
