Brad King 327490e698 enable_language: Allow CMakeDetermine<LANG>Compiler module to fail early 
If the module reports a FATAL_ERROR, skip the rest of the steps to
enable the language to avoid unnecessary following error messages.

Stephen Kelly ff015ee11e Genex: Report error if a target file is needed to evaluate link libraries. 
Constructs such as

 target_link_libraries(foo $<$<STREQUAL:$<TARGET_FILE:foo>,foo.so>:bar>)

segfault before this patch.

Brad King 56148fd2bc Do not crash on SHARED library without language (#13324) 
Since commit e1409ac5 (Support building shared libraries or modules
without soname, 2012-04-22) CMake crashes on the code

 add_library(foo SHARED foo.nolang)

because the logic to lookup the language's soname flag was moved from
cmTarget::GetLibraryNames to cmMakefile::GetSONameFlag without its check
for a NULL language.  Restore the check for NULL.

Add RunCMake.Languages test to cover language error cases like this one.
