sqlite gem tests failing on truffleruby-head

[flavorjones]

Tests pass with truffleruby-23.1.1, but error on truffleruby-dev (v24.0.0-dev-070598d4).

See https://github.com/sparklemotion/sqlite3-ruby/actions/runs/7111938537/job/19478241596#step:7:47

1) Error:

Test in question is:

    def test_bignum
      num = 4907021672125087844
      db.execute 'CREATE TABLE "employees" ("token" integer(8), "name" varchar(20) NOT NULL)'
      db.execute "INSERT INTO employees(name, token) VALUES('employee-1', ?)", [num]
      rows = db.execute 'select token from employees'
      assert_equal num, rows.first.first
    end

(the exception is thrown from the INSERT statement)

I haven't bisected, but looking at the git log, 8404d4f jumps out to me as a possible commit for introducing this behavior change.

Thank you for the report.
It is indeed likely related to that commit or at least to the Fixnum limit.
I have also reviewed all other similar cases and fixed them.

Fix in #3354.

BTW here is some context: it used to be that TruffleRuby declared Fixnum to be the entire signed 64-bit long range ([-2**63,2**63[) since Java long is used internally, but that doesn't really work in the C API because there is some expectation that all fixnums can be represented as tagged pointers and so have 1 less bit.
So then in the C API there are 3 cases, fit in Fixnum ([-2**62,2**62]), real Bignum (|x|>2**63) and "in-between" which is what we hit here, which is represented as a long in Java but is not a Fixnum from the C API POV.
So the fix changes how to call a method on such a long, which is not a Ruby object from the interop POV but an interop primitive (which has no language).

Thank you!
