Stack manipulation macro
...
Uses a variant of Dijkstra's, with a few pruning mechanics, to find a path of instructions between the two stack states. We don't explicitly store the graph though.
The Dijkstra implementation is somewhat inspired by the `pathfinding` crate. That crate doesn't quite fit our needs though.
If we need to make it faster later, there are a lot of allocations and clones that we could probably eliminate.

Add a mload_kernel_code_u32 macro
...
Intended for loading constants in SHA2, and maybe RIPEMD.
Sample usage
```
// Loads the i'th K256 constant.
%macro k256
// stack: i
%mul_const(4)
// stack: 4*i
PUSH k256_data
// stack: k256_data, 4*i
ADD
// stack: k256_data + 4*i
%mload_kernel_code_u32
// stack: K256[4*i]
%endmacro
k256_data:
BYTES 0x42, 0x8a, 0x2f, 0x98
BYTES 0x71, 0x37, 0x44, 0x91
...
```
Untested for now since our interpreter doesn't have the needed memory support quite yet.

Add custom opcodes
...
- `GET_STATE_ROOT` and `SET_STATE_ROOT` deal with the root of the state trie, and will be called from storage routines. Similarly `GET_RECEIPT_ROOT` and `SET_RECEIPT_ROOT` deal with the root of the receipt trie.
- `PANIC` enables an unsatisfiable constraint, so no proof can be generated.
- `GET_CONTEXT` and `SET_CONTEXT`, used when calling and returning
- `CONSUME_GAS` charges the sender gas; useful for cases where gas calculations are nontrivial and best implemented in assembly.
- `EXIT_KERNEL` simply clears the CPU flag indicating that we're in kernel mode; it would be used just before a jump to return to the (userspace) caller.
- `MLOAD_GENERAL` and `MSTORE_GENERAL` are for reading and writing memory, but they're not limited to the main memory segment of the current context; they can access any context and any segment. I added a couple macros to show how the they would typically be used.
There may be more later, but these are the ones I think we need for now. I tried to fill in smaller invalid sections of the decoder's tree, as Jacqui suggested, while keeping related opcodes together. We can fine tune it when the opcode list is more stable.
These are all intended to be priviledged, i.e. they will be treated as invalid if used from userspace, for compatibility as well as (in some cases) security reasons.
