Move Compiler structure to own module.

[ibuclaw]

And I propose that this should be the home of genCmain (which closes issue 15374), as well as other free functions called by the frontend, but implemented by the driver/backend in a way that isn't compatible across compiler implementations.

Thanks for your pull request, @ibuclaw!

I don't see any reason not to do this, but it could probably use more substance to motivate it. What's preventing moving genCmain now?

If someone from core maintainers says OK, then I'll do the work and move functions across.

I like that idea. Should the new file be added to any makefiles?

Right, once there's actually data in the module that needs compiling. :-)

It should still be added to the list of modules right now, rather than placing the burden on whoever maybe just makes a small change to the module in the future.

I am hugely in favor of this. It would be very helpful for the DMD as a library project.

I didn't know there already was a PR doing a similar thing : #7524 . Any way seems like we need this so we should merge one or the other.

Well merge this then as it's one better. ;-)

In any case, point is that nothing in mars.d is useable in other compilers.

Added to make files, and split out into own header.

Thanks! Looks good! It seems that we are all unanimously in favor of this?

I hope so, so that I can start populating it.
