Brad King 5db99e8708 Add CheckLanguage module 
Define a "check_language(<lang>)" macro to test whether <lang> can be
enabled.  Cache the result in CMAKE_<lang>_COMPILER.  Add a test case
covering expected results.

Rolf Eike Beer ec631d5043 add a test that loops through most Find* modules 
This allows easy spotting of modules that output crappy messages and the
like.

Rolf Eike Beer 8e1f376782 add a test for Check{,CXX}SymbolExists 
Now that we think that CheckSymbolExists really works for all cases it is time
to prove that. If this code fails too many other things will break.

Brad King 8e756d2b9b Tolerate cycles in shared library link interfaces (#12647) 
Since commit 183b9509 (Follow all dependencies of shared library private
dependencies, 2011-12-14) we honor LINK_INTERFACE_LIBRARIES when
following dependent shared libraries.  The link interface properties may
form a cycle if set incorrectly by a project.  Furthermore, the property
LINK_DEPENDENT_LIBRARIES may form a cycle if set incorrectly by hand
(though CMake should never generate one).  In either case, do not follow
the cycle forever when following the dependent shared library closure.
We only need to add dependency edges to the constraint graph once.

Add "LinkInterfaceLoop" test to cover this case.

Brad King 9a20abf04a Add infrastructure for CMake-only tests 
Some tests only need to run CMake to configure and generate a build
tree, but not actually perform the build.  Add a new "Tests/CMakeOnly"
directory dedicated for this purpose.  Add a helper script to drive each
test by creating a fresh build tree and running CMake on it.  Add macro
"add_CMakeOnly_test" to help create tests using the script.
