In a typical buildworld context that uses the system toolchain
for its build activity, more relevant is the likes of what is
in /usr/lib/clang/*/ :

# find -s / -name "*mmintrin.h" -print | less
/usr/lib/clang/19/include/ammintrin.h
/usr/lib/clang/19/include/emmintrin.h
/usr/lib/clang/19/include/immintrin.h
/usr/lib/clang/19/include/mmintrin.h
/usr/lib/clang/19/include/nmmintrin.h
/usr/lib/clang/19/include/pmmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/emmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/immintrin.h
/usr/lib/clang/19/include/ppc_wrappers/mmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/nmmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/pmmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/smmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/tmmintrin.h
/usr/lib/clang/19/include/ppc_wrappers/xmmintrin.h
/usr/lib/clang/19/include/smmintrin.h
/usr/lib/clang/19/include/tmmintrin.h
/usr/lib/clang/19/include/wmmintrin.h
/usr/lib/clang/19/include/xmmintrin.h
. . .

Those are in a place where <. . .> notation would look
for them if the system toolchain is in use, at last as
I understand things.

But . . .

What version of clang/clang++ is the building machine using?
What version of clang/clang++ is the new system to be using?

It may be that LLVM 18 needs to build the bootstrap materials
for LLVM 19, which in turn do the normal build from that
partial context. You are not explicit about the upgrade
context that you are in or what toolchain that you are using.
