gn build: Add build files for most clang-tools-extra unit tests

[mbonadei]

LGTM, just a small style comment.

Why don't we use output_name here as well? It seems to be available for executables (https://gn.googlesource.com/gn/+/master/docs/reference.md#target-declarations-executable_declare-an-executable-target-variables). The current style seems to be lisp-case for target names and have output_name matching the cmake build.

Thanks!

That's a good question. phosek asked about this too here: http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20181231/614211.html

I don't think there's a really good reason for this. I don't remember why I did it this way.

Trying to come up with a justification after the fact: A weak reason is that for static libraries it doesn't really matter what they're called on disk (other than to llvm-config's lit tests, which is why the GN build matches the cmake build -- else I wouldn't set the output name there), but for executables you need to know the name of the executable to run it, and it's maybe nice if the target has the same name as the executable for that reason.
