[PATCH] RISC-V: Remove the priority in FMV ASM name mangling

[Yangyu Chen]

We don't need to add priority in ASM name mangling, keeping this might
cause an issue if we call another MV clone directly but only one place
has the priority declared.

gcc/ChangeLog:

        * config/riscv/riscv.cc (riscv_mangle_decl_assembler_name): Remove
        priority in fmv asm name mangling.
