lit: warn when passed invalid pathname
It would previously say things like warning: input 'test/Frontend/foo.c' contained no tests and have the user pull their hair trying to figure out what's wrong with that file. This patch changes the message to the much clearer: warning: no such file or directory: 'test/Frontend/foo.c' Differential Revision: http://reviews.llvm.org/D4097 llvm-svn: 210597
