Difference in generated results between Serialization Flow and Binder Framework

[SpriteOvO]

Reproduce steps

1. Checkout branch binder-again.

2. t1/nix/t1/default.nix

   Line 81 in 925e01e

   mlirbc = innerSelf.callPackage ./mlirbc.nix { target = "subsystem"; use-binder = true; };

   
   Specifying use-binder = true; to use the Binder Framework, commenting it out to use the old Serialization Flow.
3. Run nix build '.#t1.blastoise.subsystem.rtl' -L for both flow, generated files will be under ./result directory.
4. diff files between the 2 ./result directories, see differences.
