Revert commit 5c3a93ab88 (Intel: Add Intel Clang compiler
identification, 2020-09-29, v3.19.0-rc1~68^2). The compiler has already
been released, and is more usable with CMake by pretending to be
upstream Clang than by identifying it as a compiler for which we have
not implemented support.
Issue: #21551
version.txt is gone from CUDA 11.1 installations, but the rest is the same.
Instead of looking for version.txt look for <CUDA path>/nvvm/libdevice, which
is the main thing that Clang requires (though it also checks for the existence
of bin and include).
Fixes#21353.
Revert commit 74b1c9fc8e (Explicitly specify language flag when source
LANGUAGE property is set, 2020-06-01, v3.19.0-rc1~722^2) and the lookup
tables from its two immediate ancestors. The purpose of that change was
to convert an explicit `LANGUAGE` source file property into an explicit
language specification compiler flag like `-x c`. This seems reasonable
since the property is documented as meaning "indicate what programming
language the source file is". It is also needed to help compilers deal
with non-standard source file extensions they don't recognize.
However, some projects have been setting `LANGUAGE C` on `.S` assembler
source files to mean "use the C compiler". Passing `-x c` for them
breaks the build because the `.S` sources are not written in C. These
projects should be updated to use `enable_language(ASM)`, for which
CMake often chooses the C compiler as the assembler when using
toolchains that support it (which would have to be the case for projects
using the approach).
Revert the change for now to preserve the old behavior for such projects.
We can re-introduce it with a policy in a future version of CMake.

Many environment variables were documented late and got
assigned wrong versions by the script.
(The whole Help/envvar section was only added in 3.10).
Issue: #19715
There was an ambiguity in the wording with the meaning of "or" typically
meaning exclusive-or in prose. Instead, ensure that the easiest parsing
is clear that the directory part is always removed.
If a path argument with no -S or -B leads to a cache directory,
use that directory as the binary directory. Otherwise, use the
binary directory from the preset.
Fixes: #21311
Make this field separate for both architecture and toolset. Allow
architecture and toolset to be either strings or objects with value
and strategy fields.
