I created a fresh build using everything in v1.87 plus the latest Espressif SDK v2.0.0 with the latest patch. This build has crypto support but not graphics. Both just don't fit into flash :-(. The esp8266 runs at 160Mhz and Espruino gets 1700 jsvars. The free heap comes out to ~8KB and the build uses lwip_536 so packet buffers aren't as big as they would be otherwise.
I have not done extensive testing, please let me know if I botched something. You can download the build from http://www.espruino.com/binaries/travis/b3dc05b5378a9182eea44e8c47b15c54e788037d/espruino_1v87.tve_master_b3dc05b_esp8266.tgz and I opened a PR for Gordon https://github.com/espruino/Espruino/pull/925
