475663f039 Only intern constants upon compilation entry 
Before this commit the Prism compiler would try to intern constants
every time it re-entered. This pool of constants is "constant" (there is
only one pool per parser instance), so we should do it only once: upon
the top level entry to the compiler.

This change does just that: it populates the interned constants once.

2d9db72d37 Write to constant path, call, and index in rescue 
When compiling a rescue reference, you can write to a constant
path, a call, or an index. In these cases we need to compile the
prefix expression first, then handle actually doing the write/call.

371256775f Anonymous rest nodes should increase the local table size 
When we calculate the local table size, we need to account for anonymous
"rest" parameters.  Since they don't have a name, they won't be in the
"locals" table that Prism provides, but we need to reserve room for them
anyway.

55b7121358 [PRISM] Frozen string literals should be fstrings

47ff4a1658 [PRISM] Blocks should track the found local depth 
Rather than rely purely on local depth offset. This is because we can't
assume a specific depth offset for all variable accesses happening
within a block in the same way that we can for rescue/ensure/for or
other nodes that push scopes.

This is because block parameters are defined in the scope level, so we
always need to start from the top most scope and walk backwards.

b8074c2f04 [PRISM] Fix incorrect instructions for default_proc= 
This is kind of specific and was found via debugging ruby/prism#2061 but
does not actually fix that issue.

The change here checks for `!popped` for the additional instructions
that are normally added for nodes with the `attribute_write` flag.

I also removed the extra catch table by deleting the
`ISEQ_COMPILE_DATA(iseq)->catch_except_p = true;` line. I'm...not
entirely sure why it was added but it doesn't match the upstream
compiler
[code](92b10f5be7/compile.c (L887-L892)).

The changes here unfortunately don't improve the test failures mentioned in
the linked issue so we still have other issues with instructions for
hashes.

d07fdc5ede [PRISM] Fix keyword hash handling in method calls 
* Start using the renamed `PM_KEYWORD_HASH_NODE_FLAGS_SYMBOL_KEYS` flag
to check if all keys of the keyword hash node are symbols.
* For arguments passed as a hash, start marking them as `KW_SPLAT_MUT` only if the number of entries in the hash is greater than 1 (which is what the old compiler used to do).

5a66832952 [Prism] Fix cvar or assignment instructions 
The instructions for `PM_CLASS_VARIABLE_OR_WRITE_NODE` were incorrect as
they were missing a `putnil`, a `defined`, and a `branchunless`.

I verified this is fixed via the instructions and running the following:
`RUBY_ISEQ_DUMP_DEBUG=prism make test/csv/interface/test_read_write.rb`.

These new instructions can't go in the defined function because
`defined?(@@fop ||= 1)` should return "assignment" not "class variable".

e71f011713 [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

110dbf62ac [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)) shows that should
use `getglobal.

```

I'm struggling with writing a failing test, but the before/after
instructions show that `getglobal` is correct here. I compared the
instructions for the  other `InterpolatedMatchLastLine` node tests
and they also used `getglobal`. I've edited the existing
`InterpolatedLastMatchLineNode` test so that it will use that instruction when
copied out of the test. Without the quotes it thinks it's just a
`MatchLastLineNode`.

Incorrect instructions:
