MIPS: Convert cross-mode BAL to JALX
Convert cross-mode regular MIPS and microMIPS BAL instructions to JALX,
similarly to how JAL instructions are converted.
bfd/
* elfxx-mips.c (mips_elf_perform_relocation): Convert cross-mode
BAL to JALX.
(_bfd_mips_elf_relocate_section) <bfd_reloc_outofrange>: Add a
corresponding error message.
gas/
* config/tc-mips.c (mips_force_relocation, mips_fix_adjustable):
Adjust comments for BAL to JALX linker conversion.
(fix_bad_cross_mode_branch_p): Accept cross-mode BAL.
