Piyou Chen f658c1bf4a Recommit "[RISCV][FMV] Support target_version" (#111096)" (#111333) ...

Fix the buildbot failure caused by heap use-after-free error.

Origin message:

    This patch enable `target_version` attribute for RISC-V target.

    The proposal of `target_version` syntax can be found at the
    https://github.com/riscv-non-isa/riscv-c-api-doc/pull/48 (which has
    landed), as modified by the proposed
https://github.com/riscv-non-isa/riscv-c-api-doc/pull/85 (which adds the
    priority syntax).

`target_version` attribute will trigger the function multi-versioning
    feature and act like `target_clones` attribute. See
https://github.com/llvm/llvm-project/pull/85786 for the implementation
    of `target_clones`.
