947194aacb [PRISM] Fix memory leak of ST table 
This commit fixes a memory leak in rb_translate_prism because the ST
table is never freed. There are still more memory leaks which still need
to be fixed.

For example:

    10.times do
      100_000.times do
        RubyVM::InstructionSequence.compile_prism("")
      end

      puts `ps -o rss= -p #{$$}`

78ad91f83f [Prism] Fix more method call argumnents 
In #2087 it was noted that there was a bug in the number of arguments in
`SplatNode` and `KeywordHashNode`. I looked into this with Aaron before
the linked PR was merged and we found a bunch of cases that weren't
working quite right. This PR aims to fix some of those cases, but there
may be more.

A splat argument followed by a positional argument will concat the array
until the end or unless the argument is a kwarg or splat kwarg. For
example

```
foo(a, *b, c, *d, e)
```

Will have an `argc` of 2, because `b`, `c`, `d`, and `e` will be
concatenated together.

```
foo(a, *b, c, *d, **e)
```

Will have an `argc` of 3, because `b`, `c`, and `d` will be concatenated
together and `e` is a separate argument.
