CRuby test failure: TestAllocation

We need to implement all of the same recent optimizations to setup_args that were added in 3.4. This largely involves avoiding array and hash allocations. This is done through checking for specific patterns and using a combination of flags and instructions like pushtoarray and concattoarray.

In order to test changes, you will need to apply to following diff to ruby/ruby (copy into a file like prism.patch and run git apply prism.patch):

diff --git a/internal/parse.h b/internal/parse.h
index fdf2a10183..88230fd177 100644
--- a/internal/parse.h

 #ifndef RB_DEFAULT_PARSER
-#define RB_DEFAULT_PARSER 0

 #endif

 #ifdef UNIVERSAL_PARSER

Then, to run the individual tests, run:

make -j
make test-all TESTS=test/ruby/test_allocation.rb TESTOPTS='-n /test_no_parameters/'

ruby / prism
