clang_15 appears to not cross compile in the build!=(host==target)
case due to two problems, which this commit fixes:
- It trips -Wmaybe-uninitialized on recent gcc, but only in the
build!=host case (likely due to #ifdefs)
- Two more buildPlatform tools have been added:
clang-tidy-confusable-chars-gen and clang-pseudo-gen

Port of 44165d3657 ("llvmPackages_{14, git}.clang: add nostdlibinc flag")
to Clang 15. It was originally thought this wasn't needed[1], but it is,
to fix expressions like the following:
with import ./. {};
llvmPackages_15.libcxxStdenv.mkDerivation {
name = "libcxx-stdenv-c++-test";
dontUnpack = true;
input = ''
#include <cstdlib>
int main() {
std::abort();
return 0;
}
'';
passAsFile = [ "input" ];
installPhase = ''
$CXX -c -o $out -x c++ $inputPath
'';
}
