--- Comment #2 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
Confirm.  But option save/restore has been always implemented:

    .section    .gnu.lto_.opts,"",@progbits
    .ascii  "'-fno-openmp' '-fno-openacc' '-fno-pie' '-fcf-protection"
    .ascii  "=none' '-mabi=lp64d' '-march=loongarch64' '-mfpu=64' '-m"
    .ascii  "simd=lasx' '-mcmodel=normal' '-mtune=loongarch64' '-flto"
    .ascii  "'\000"

So -msimd=lasx is correctly recorded.  Not sure why it does not work.
