There's no need for macro `toSymbolName` to convert fork enum values to their
presentation texts (logging etc) then re-parse them back to a fork enum value.
`asFork` is already used in the same function and works without these steps,
so use it consistently.
Same applies to `op.toSymbolName` and `asOp`.
This makes the code simpler, and removes a text pattern-matching requirement.
The patch has been checked to confirm it doesn't change the compiled code.
Motivation: The forks list will be removed from VM because it is used outside
the VM as well. Doing so highlighted vm2's `toSymbolName`. It's not needed,
and it's best if the VM doesn't constrain text strings used outside the VM

why:
the v2 prefix of the file name was used as a visual aid when
comparing vm2 against vm sources
details:
all renamed v2*.nim sources compile locally with the -d:kludge:1 flag
set or without (some work with either)
only sources not renamed yet: v2state_transactions.nim
why:
the new implementation lost more then 25% execution time on the test
suite when compared to the original VM. so the handler call and the
surrounding statements have been wrapped in a big case statement similar
to the original VM implementation. on Linux/x64, the execution time of
the new VM2 seems to be on par with the old VM.
details:
on Linux/x64, computed goto works and is activated with the -d:release
flag. here the execution time of the new VM2 was tested short of 0.02%
better than the old VM. without the computed goto, it is short of
0.4% slower than the old VM.
why:
activate NIM comments needed re-write. as there is no advantage in using
the macro replacing a few missing op-codes by "Nop##" name symbols, the
macro wrapper has been removed.
details:
when explicitly accessed by numeric value ##, missing Op enum entries
result in a symbol name something like "Op ##".
rather than implicitly using a macro to fix the op-codes list, missing
entries are detected at compile time when a fatal exception is thrown.
the static compile time check verifies that
all op-codes 0 .. 255 are defined
op code name/mnemonic has at least 2 chars and starts with a capital
op code name/mnemonic is not NIM auto-generated (i.e. has a space)
also, original '#' comments are exposed as doc comments '##'
