[Bug target/31388] New: ICE building libiberty multilib for mips16 multilibs

[nickc at redhat dot com]

I recently ran across an ICE building a target libiberty for one of
the multilibs of the mips64vrel-elf toolchain:

     .../libiberty/regex.c: In function 'byte_re_match_2_internal':
     .../libiberty/regex.c:7481: error: insn does not satisfy its constraints:

    (set (reg:SI 5 $5)
         (lo_sum:SI (reg/f:SI 1104)
                    (symbol_ref:SI ("byte_reg_unset_dummy") [flags 0x6]
