Detect clang-cl as msvc-like, not clang-like

Handle clang's cl or clang-cl being in PATH, or set in CC/CXX

Future work: checking the name of the executable here seems like a bad idea.
These compilers will fail to be detected if they are renamed.

v2:
Update compiler.get_argument_type() test
Fix comparisons of id inside CCompiler, backends and elsewhere

v3:
ClangClCPPCompiler should be a subclass of ClangClCCompier, as well

Future work: mocking in test_find_library_patterns() is effected, as we
now test for a subclass, rather than self.id in CCompiler.get_library_naming()
