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`.
