A version scheme is a class that inherits from Version and reimplements
Version#<=>. This will allow formulae to specify a custom comparison
method that will be used instead of the default, for cases where the
default is insufficient.
Tests that expect Formula#path to resolve to a real path should use
TestBallWithRealPath; TestBall gets its original behavior back, fixing a
failing test in test_formula_install.

Tapped formulae that dupe those in core now display the correct URL when
invoked like `brew info homebrew/dupes/openssl`.
This also fixes the broken `brew info` test.

- Formulae can now declare failures on any compiler.
- FailsWithLLVM and associated formula elements have been moved to
compat.
