ZJIT: Compile `IsA xyz, String`, `IsA xyz, Array`, `IsA xyz, Hash` into load+compare

[tekknolagi]

We can check against T_STRING, T_ARRAY, T_HASH, etc

[tekknolagi]

We'll need also to check if the object is immediate/false first

Thank you!

We will probably long-term want to get this into HIR instead of LIR, but we can't really support that right now
