[lit] check-lit compatibility with multi-config CMake generators

Authored by gbedwell on Aug 3 2017, 4:42 AM.


Multi-configuration CMake generators such as Visual Studio or Xcode do not
specify a build config at configure time, but let the user choose at build
time.  In these cases binaries go into bin/${Configuration} rather than
bin/.  Prior to this commit, check-lit would fail when using multi-configuration
generators as it did not know how to resolve bin/${Configuration} in order
to find tools such as FileCheck.  This commit teaches it to resolve
llvm_tools_dir within lit using the value specified with --param

This commit supersedes D36212 after discussion in that review. Essentially we're just using the strategy seen elsewhere to deal with this issue (e.g. llvm/test/Unit )

Looks good, but I don't have environments to check actually.
