lit/setup.py: Install as llvm-lit (as cmake expects it)

[mgorny]

Summary

Modify the setup.py for lit to install the entry point as llvm-lit (instead of lit) since this is the name expected by functions in AddLLVM.cmake.

[• ddunbar]

This isn't correct, llvm-lit is something else (an llvm specific entry point to lit that knows the object directory). That doesn't belong in the base lit project.

[mgorny]

So what should be done? Should the cmake functions be modified to look for both llvm-lit and lit?

I'm talking of add_lit_target() that is using:

find_program(LIT_COMMAND llvm-lit)

when LLVM_MAIN_SRC_DIR is unset.
