llvm dev - Jan 2016 - Windows binaries and LLVM_INSTALL_TOOLCHAIN_ONLY

This is mostly to Hans since he builds these AIUI, but would be worth
getting others' opinions too. I'd like to ask whether building the
Windows
binaries *without* LLVM_INSTALL_TOOLCHAIN_ONLY could be considered and
tried. Would the result be a prohibitive amount larger than the current
installer? LLVM is an incredibly useful set of libraries and has many use
cases, including on Windows, beyond just a clang.exe add-in for Visual
Studio.

For those of us downstream users who consume LLVM as a library and aren't
doing development on LLVM itself every day, having libraries and headers
ready to go from a binary download would save a few hours of getting-up-
and-running time.

Thanks,
Tony

This comes up now and then.

Yes, the packages would be a lot bigger, but IIRC the problem is also
that we don't have a good way to build to build LLVM into a shared
library on Windows that's suitable for shipping. I don't remember the
details here; maybe Reid does.

Thanks,
Hans

Some of the other platforms' binaries look like they also ship static
libraries, and that would be more useful than no libraries at all IMO.

I believe the issue with the dll build is marking symbols for dllexport.
