new devel/llvm-lit

Hi,

To test OpenMP I need the LLVM test tools. I decided to create a
new port, instead of using the exiting llvm ports. It reuses the
llvm-project distfile, but compiles and tests only what I need. It
is a bit tricky as it is half cmake and half python. I use the
newest llvm version, hoping that the test tools are compatible.

ok to import llvm-lit?

LLVM integrated tester

Description:
lit is a portable tool for executing LLVM and Clang style test suites,
summarizing their results, and providing indication of failures. lit is
designed to be a lightweight testing tool with as simple a user interface
as possible.
