Some work on speculative execution (#1552)
* Recreating some of the speculative-execution code.

Not really using it yet. Also there's some new inefficiency in
memory.nim, but it's fixable - just haven't gotten around to it yet.

The big thing introduced here is the idea of "cells" for stack,
memory, and storage values. A cell is basically just a Future (though
there's also the option of making it an Identity - just a simple
distinct wrapper around a value - if you want to turn off the
asynchrony).

* Bumped nim-eth.

* Cleaned up a few comments.

* Bumped nim-secp256k1.

* Oops.

* Fixing a few compiler errors that show up with EVMC enabled.

refactor touched accounts, selfdestruct, and log
simplify EVM and delegete those things to accounts cache.
also no more manual state clearing, accounts cache will be
responsible for both collecting touched account and perform
state clearing.

align accounts cache with EIP158/161
Some nomenclature used in accounts cache are not what described
in EIP158/161, therefore causing confusion and introduce bugs.
Now it should be fixed.

Silence some compiler gossip -- part 6, evm (#1462)
* Silence some compiler gossip -- part 6, evm

details:
  Adding some missing exception annotation

* Update evmc cases

why:
  were previously missing

* Increase Windows stack needed to run EVMC unit tests

why:
  After annotating functions to trace exceptions some unit tests started
  to fail on Windows without clear error report.

  EVMC works recursively and now there seems to be a stack problem
  reported by the nim compiler. Increasing the NIM stack ass sugessted by
  NIM (using -d:nimCallDepthLimit=###) had some effect but no clear
  solution.

Note that this patch set unrolls some NIM compiler settings
