With opaque pointers, we cannot use the pointer element type to

types are used to determine the location size.

as the type is not considered part of the sorted string anymore.

[clang-tools-extra] Reuse llvm_config.use_clang() to set up test environment
This replaces a bunch of duplicate logic to set up environment variables
and a few substitutions.
It does a little more than we were doing previously:
- searching for clang and setting up substitutions for it
- setting up some substitutions for target triples, which are
potentially useful but not actually used
clangd has been happily using this for its tests for a while.

[libc++] Add workaround to avoid breaking users of <span> when <ranges> are disabled
Back in
3a208c68942e, we implemented the range-based constructor for <span>.
However, in doing so, we removed a previous non-standard constructor that
we provided before shipping <ranges>. Unfortunately, that breaks code that
was relying on a range-based constructor until we ship all of <ranges>.
This patch reintroduces the old non-conforming constructors and tests
that were removed in
3a208c68942e and uses them whenever <ranges> is
not provided (e.g. in LLVM 14). This is only a temporary workaround
until we enable <ranges> by default in C++20, which should hopefully
happen by LLVM 15.
The goal is to cherry-pick this workaround back to the LLVM 14 release
branch, since I suspect the constructor removal may otherwise cause
breakage out there, like the breakage I saw internally.
We could have avoided this situation by waiting for C++20 to be finalized
before shipping std::span. For example, we could have guarded it with
something like _LIBCPP_HAS_NO_INCOMPLETE_RANGES to prevent users from
accidentally starting to depend on it before it is stable. We did not
have these mechanisms when std::span was first implemented, though.

up an imported CMake target. Accordingly, the smoke test fails, since it
can't find the libcurl (or its static dependencies).
This changes the compile smoke test to refer to the imported library
instead; this should in turn bring in the necessary include and library
