This PR adds a function which converts the language to string. This is
intended to be used by the z/OS target, see the patch here:

Currently CUDA/HIP defines their own language standards in
LanguageStandards.def but they are redundant. They are the same as stdc++14.
The fact that CUDA/HIP uses c++* in option -std= indicates that they have the
same language standards as C++. The CUDA/HIP specific language features are
conveyed through language options, not language standards features. It makes
sense to let CUDA/HIP uses the same default language standard as C++.

This makes CLANG_DEFAULT_STD_C(XX) always be defined, defaulting to
lang_unspecified, so you are forced to check its value instead of using
an #ifdef. This should help avoid accidentally omitting the include in
places where that's important, so that the default language version bug
isn't re-introduced.

This is necessary in order to pick up the default C/C++ standard from
the CLANG_DEFAULT_STD_C(XX) defines. This fixes a bug that was
introduced when this default language standard code was moved from
Frontend to Basic, making compilers ignore the configured default
language version override.
Fixes a bug introduced by D121375.

The function is moved from clangFrontend to clangBasic, which allows tools
(e.g. clang pseudoparser) which don't depend on clangFrontend to use.

This patch is a prerequisite for using LangStandard from Driver in
https://reviews.llvm.org/D64793.
It moves LangStandard* and InputKind::Language to Basic. It is mostly
mechanical, with only a few changes of note:
- enum Language has been changed into enum class Language : uint8_t to
avoid a clash between OpenCL in enum Language and OpenCL in enum
LangFeatures and not to increase the size of class InputKind.
- Now that getLangStandardForName, which is currently unused, also checks
both canonical and alias names, I've introduced a helper getLangKind
which factors out a code pattern already used 3 times.
The patch has been tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11,
and x86_64-pc-linux-gnu.
There's a companion patch for lldb which uses LangStandard.h
(https://reviews.llvm.org/D65717).
While polly includes isl which in turn uses InputKind::C, that part of the
code isn't even built inside the llvm tree. I've posted a patch to allow
for both InputKind::C and Language::C upstream
(https://groups.google.com/forum/#!topic/isl-development/6oEvNWOSQFE).
