    MIPS/LD: Skip overflow check for %pcrel_hi relocations

    Overflow checks were removed for all hi16 relocations except PC-relative
    high relocations per PR ld/16720.  Remove overflow checks from %pcrel_hi
    relocations so that we can correctly handle negative offsets from PC.

    bfd/
        * elfxx-mips.c (mips_elf_calculate_relocation) <R_MIPS_PCHI16>:
        Remove overflow check.

    ld/
        * testsuite/ld-mips-elf/undefweak-overflow.s: Remove test case
        for pcrel_hi/pcrel_lo.
        * testsuite/ld-mips-elf/undefweak-overflow.d: Update to match.
        * testsuite/ld-mips-elf/reloc-pcrel-r6.s: New test source.
        * testsuite/ld-mips-elf/reloc-pcrel-r6.d: New test linker script.
        * testsuite/ld-mips-elf/reloc-pcrel-r6.ld: New test.
        * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.
