Adrien Destugues c8ecfce34c jam: add an option to generate compile_commands.json 
Based on Boost Jam patch: https://github.com/boostorg/build/pull/133
retrofitted to our version. Only the rules whose name contains Cc or C++
are stored there. This can be improved if it's not good enough.

The commands are generated only as they are run. Unfortunately I think
with Jam there isn't really a way to do otherwise.
