* 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
