Jordan Hrycaj 9b70ab5f8f update handler prototype using call-by-reference argument
why:
  this allows for passing back information which can eventually be
  used for reducing use of exceptions

caveat:
  call/create currently needs to un-capture the call-by-reference
  (wrapper) argument using the Computation reference inside

Jordan Hrycaj b388e966cc simplify interpreter_dispatch.nim code
details:
  replace generated macro loop/switch by explicit call using the
  fork/op handler matrix (encapsulated via opHandlersRun() function)

Jordan Hrycaj 51587208b4 verifying new op handler tables layout against original tables
why:
  the previous approach was replacing the function-lets in
  opcode_impl.nim by the particulate table handlers. the test
  functions will verify the the handler functions are sort of
  correct but not the assignments in the fork tables.

  the handler names of old and new for tables are checked here.

caveat:
  verifying tables currently takes a while at compile time.

Jordan Hrycaj 5e7d4ac9c5 experimental op handlers table (tbc.)
details:
  the op handler table is accessible via op_handlers.nim module

  op handler function implementations are found in the op_handlers/
  sub-directory

kludge:
  for development and pre-testing, any new module can be individually
  compiled setting the kludge flag using -d:kludge:1. this causes some
  proc/func replacements in turn allowing for omitting imports that would
  otherwise cause a circular dependency. otherwise individual compilation
  would fail.

  in order to prove the overall correctness of the code, the
  op_handlers.nim is imported by opcodes_impl.nim when compiling all,
  nimbus or test.
