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()

Replace several checks against GCC_MINGW or (GCC_MINGW, GCC_CYGWIN) with
is_windows_compiler instead, so that clang and other gcc-like compilers
using MinGW work appropriately with vs_module_defs, c_winlibs, and
cpp_winlibs.
Fixes #4434.

We do this with `std_ver=vc++NM` - `vc++` does not add `/permissive-`,
while `std_ver=c++NM` adds `/permissive-`.

* Enums are strongly typed and make the whole
`gcc_type`/`clang_type`/`icc_type` distinction
redundant.
* Enums also allow extending via member functions,
which makes the code more generalisable.

It's fairly common on Linux and *BSD platforms to check for these
attributes existence, so it makes sense to me to have this checking
build into meson itself. Autotools also has a builtin for handling
these, and by building them in we can short circuit cases that we know
that these don't exist (MSVC).
Additionally this adds support for two common MSVC __declspec
attributes, dllimport and dllexport. This implements the declspec
version (even though GCC has an __attribute__ version that both it and
clang support), since GCC and Clang support the MSVC version as well.
Thus it seems reasonable to assume that most projects will use the
__declspec version over teh __attribute__ version.

* The current version matching logic is brittle
with respect to Clang. LLVM and Apple Clang use
slightly different but nowadays overlapping
version ranges. Instead, we now just check whether
the compiler supports the given `-std=` variant
and try its respective fallback instead of
testing version ranges.

* GCC 4.8 and Clang 3.2, 3.3, 3.4 only understand
`-std={c,gnu}++1y` for enabling C++14 dialects.
GCC 4.8 is especially important as it is the basis
of RHEL/CentOS 7.

Parent class could have common options for all compilers, and we'll soon
add some.

super(VisualStudioCCompiler, self) calls CPPCompiler and that's what we
want to avoid.

According to Python documentation[1] dirname and basename
are defined as follows:
os.path.dirname() = os.path.split()[0]
os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.

has_argument and other similar methods of compiler objects only support
checking compiler flags. If they are used to check linker flags, the
results are very likely to be wrong and developers should be warned.

See issue #2762
Adds full_version to class Compiler. If set full_version will be printed
additionally.
Added support for CCompiler and CPPCompiler
Added support for gcc/g++, clang/clang++, icc.

CCache requires this flag when building with precompiled headers.
Without it, the preprocessor fails and CCache fallbacks to running the
real compiler.
Users still need to set 'sloppiness' to 'pch_defines,time_macros' in
their ccache.conf file for CCache to cache builds that use precompiled
headers. See the CCache manual for more info:
https://ccache.samba.org/manual.html#_precompiled_headers

Use this when we print language-related information to the console and
