Enable W ^ E in V8 for node.js build #40
Description
As mentioned on twitter https://twitter.com/EdSchouten/status/993144257438502912
cloudabi executables require W^E memory
V8 runtime enabled this by default in this commit v8/v8@bf19e60
However there seems to be a conflict with WASM so the feature has been put behind a flag for now
https://bugs.chromium.org/p/v8/issues/detail?id=7272
The flag is --write-protect-code-memory
I would have thought patching this line https://github.com/nodejs/node/blob/82e475dc75751df08d80bd6e25926bd25c1794f2/deps/v8/src/flag-definitions.h#L675 to true should be enough to get this up and running but any thoughts appreciated.
