[PRISM] Fix bugs in compiling optional keyword parameters
...
This PR fixes two bugs when compiling optional keyword parameters:
- It moves keyword parameter compilation to STEP 5 in the parameters
sequence, where the rest of compilation happens. This is important
because keyword parameter compilation relies on the value of
body->param.keyword->bits_start which gets set in an earlier step
- It compiles array and hash values for keyword parameters, which
it didn't previously

[Prism] Fix InterpolatedMatchLastLine Instructions
...
I looked at this at RubyConf with Kevin, and we noticed that there was a
`putobject` empty string missing from the instructions. I just got back
around to implementing this and pushing a PR and while doing that
noticed that we also have a `getspecial` when we want a `getglobal`.
This change adds the `putobject` instruction and replaces the
`getspecial` with a `getglobal`. If we look at the parsetree for the
following code:
```ruby
$pit = '.oo'; if /"#{$pit}"/mix; end
```
We can see it has a `NODE_GVAR` and the [Ruby
compiler](a4b43e9264/compile.c (L10024-L10030)

[PRISM] Fix attrset edge cases
...
In some cases code may look like an attrset ID but should actually
return the value of the method, not the passed values.
In ruby/prism#2051 a flag was added when we have a attribute write call.
I used this flag to add the proper instructions when we have a real
attrset instead of using `rb_is_attrset_id` which was kind of hacky
anyway.
The value that should be returned in the newly added test is 42, not 2.
Previously the changes we had made returned 2.

This commit passes an `end` to rb_int_parse_cstr which allows us

[PRISM] Fix segv with regex once flag
...
When you have an interpolated regex with a `once` flag and local
variable is outside the block created by the `once` flag, Prism would
see a segv. This is because it was not taking the depth into account.
To fix this, we need to add 1 to the `local_depth_offset` on the
`scope`.

[PRISM] Restructure parameters on ScopeNodes
...
This commit completely restructures how we handle parameters. The
motivation for this commit was the fix compilation of MultiTargetNodes
within parameters, including nested MultiTargetNodes. A subsequent
commit will actually do the compilation for the MultiTargetNodes.
This commit's main accomplishment is restructuring the locals table
and how we account for it on the ScopeNode, specifically with regards
to hidden variables.
It has multiple steps, all commented within the code, to calculate
the locals table correctly and compile the parameters:
- Step 1: Caculate the table size for the locals
- Step 2: Populate iv index table and local table
- Step 3: Fill in parameter names of MultiTargetNodes on local table
- Step 4: Fill in method body locals on local table
- Step 5: Compile any locals

Add handling of implicit hash arguments
...
Arguments that are passed as a hash need special consideration since in certain case they are not treated as keyword arguments. For example, if a call is passing `"a" => 1` as an argument, this will be turned into an implicit hash argument and not a keyword argument.
The existing compiler checks to see if all hash nodes can be treated as keyword arguments. If they can, then it will treat them as keyword arguments. If not, then it will treat them as implicit hash arguments.
This commit implements the same logic inside the Prism compiler.

[PRISM] Fix `PM_CALL_NODE` assignment
...
This PR fixes ruby/prism#1963 . Array and variable assignment was broken
for call nodes. The change checks if the `method_id` is related to
assignment and if is adds a `putnil`, `setn` and a `pop`.
The incorrect instructions meant that in some cases (demonstrated in
tests) the wrong value would be returned.
I verified that this fixes the test mentioned in the issue
(run: `RUBY_ISEQ_DUMP_DEBUG=prism make test/-ext-/st/test_numhash.rb`)
Incorrect instructions:
