Add a test that ensures the Clang driver behaves itself when the PATH environment variable is changed to strange things out from under it. Prior to r223099 in LLVM, these test cases would crash in various ways (assert fails, stack exhaustion, etc.). llvm-svn: 223100

// These tests try to ensure that the driver operates reasonably when run with
// a strange environment. Unfortunately, it requires a normal shell and the
// 'env' command.

// REQUIRES: shell

// The PATH variable is heavily used when trying to find a linker.
Rely on fewer features of the 'env' command. Darwin only supports '-i'. I'm explicitly setting LC_ALL=C somewhat for documentation, but hopefully this also removes some host variation from the test results. llvm-svn: 223102
