As captured in issue #108044, HLSL 202x is the target language mode for
conformance for Clang. Earlier language modes will be a best effort and
prioritized after 2020x. To make this easier and reduce our testing
complexity we want to make 202x the default language mode now, and align
all earlier modes to match 202x (except where we explicitly deviate).
This change has the following concrete changes:
* All older language modes gain `CPlusPlus11` as a base
* The default language mode for HLSL sources is changed to 202x
* A few test cases are updated to resolve differences in generated
diagnostics.
Second to last change for #108044
This change adds a new HLSL 202y language mode. Currently HLSL 202y is
planned to add `auto` and `constexpr`.
This change updates extension diagnostics to state that lambadas are a
"clang HLSL" extension (since we have no planned release yet to include
them), and that `auto` is a HLSL 202y extension when used in earlier
language modes.
Note: This PR does temporarily work around some differences between HLSL
2021 and 202x in Clang by changing test cases to explicitly specify
202x. A subsequent PR will update 2021's language flags to match 202x.
Add the CIR language to the Language enum and the standard usages of it.

Previously, clang-dxc.exe would not recognize -HV as a valid argument to
DXC, and would be unable to translate the argument to a legal clang
argument. This PR implements a translation of the HV option and its
value to the appropriate clang flag and the appropriate value. It adds a
test by using the -### option to spit out the translated options, and
checks to see that the correct option was generated.

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).
