37d92b55ac Basic MPT logic
For now this contains most of the basic framework/structure. Logic for things like insertions will come later.

6a7e8d0fb0 Trie related segments and metadata
Summary of the design:
- Tries are stored as immutable, copy-on-write trees
- All trie data is stored in the `TrieData` segment. Since it's immutable, data is never modified/deleted, new versions are just appended at the end.
- In order to support reverts, each context stores a pointer to the initial state trie version, plus the initial version of each storage trie.

One variation which may be worth considering is storing the whole state trie as one big trie (with sub-tries for storage). Reverts would then be simpler - we'd replace a single pointer. I thought that approach might make hashing the trie a bit more complex, as the node associated with an account would be a special type of node, rather than just another leaf. Either approach seems reasonable though.

707e564934 Make use of mstore_txn_field in type 0 parsing
Some of the `%stack` operations are now trivial, but I kind of like keeping `%stack` since it serves as documentation as well, making comments about the stack unnecessary.

Using a method Angus described. This is mainly his idea and code, I just ported it to Rust.

616eb618f2 Support macro-local labels
Again borrowing syntax from NASM. Example from the test:

    %macro spin
    %%start:
        PUSH %%start
        JUMP
    %endmacro

One thing this lets us do is create "wrapper" macros which call a function, then return to the code immediately following the macro call, such as

    %macro decode_rlp_scalar
        %stack (pos) -> (pos, %%after)
        %jump(decode_rlp_scalar)
    %%after:
    %endmacro

I used this to clean up `type_0.asm`.

However, since such macros need to insert `%%after` beneath any arguments in the stack, using them will be suboptimal in some cases. I wouldn't worry about it generally, but we might want to avoid them in performance-critical code, or functions with many arguments like `memcpy`.
