Offending commit must have been https://github.com/llvm/llvm-project/commit/f06abbb393800b0d466c88e283c06f75561c432c

Before Gentoo adapts, it is possible to build the previous commit: EGIT_OVERRIDE_COMMIT_LLVM_LLVM_PROJECT=c2d27c89593e92f8e557f27ec02f083760eeab2d emerge -v1 llvm:15 clang:15

Currently due to https://github.com/gentoo/gentoo/commit/4cc3a44c50e3a21d55dbdd8290ec2fe5c0ef5786 you also need to remove the line with UnicodeNameMappingGenerator from llvm-15.0.0.9999.ebuild otherwise it won't build with the above workaround.

It's been fixed upstream.
