Bug

After this PR #6434 some private functions in aztec have grown 20x in the size of ACIR bytecode.

To Reproduce

use dep::aztec::macros::aztec;

#[aztec]
contract StatefulTest {
    use dep::aztec::{
        initializer::assert_is_initialized_private,
        macros::{functions::{initializer, noinitcheck, private, public, view}, storage::storage},
    };
    use dep::aztec::prelude::{AztecAddress, FunctionSelector, Map, PrivateSet, PublicMutable};
    use dep::value_note::{balance_utils, utils::{decrement, increment}, value_note::ValueNote};

    #[storage]
    struct Storage<Context> {
        notes: Map<AztecAddress, PrivateSet<ValueNote, Context>, Context>,
        public_values: Map<AztecAddress, PublicMutable<Field, Context>, Context>,
    }


    #[private]
    fn create_note(owner: AztecAddress, outgoing_viewer: AztecAddress, value: Field) {
        if (value != 0) {
            let loc = storage.notes.at(owner);
            increment(loc, value, owner, outgoing_viewer, outgoing_viewer);
        }
    }

}
