--- Comment #1 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
The function __builtin_neon_vuzpv8qi is undefined since the builtin was
removed, hence the call being emitted. The testcase hides this by passing
`-Wno-implicit-function-declaration`.
The testcase was a reduced case from pr51968. There is still an issue here
that the hard register shouldn't have been emitted, but I'll fix the testcase
in pr51968 in the meantime.
