For R_M32R_HI16_SLO, the lower 16 bits are sign extended when added to
the high 16 bytes so if the lower 16 bits are negative (bit 15 == 1) then
we must add one to the high 16 bytes (which will get subtracted off when
the low 16 bits are added).
These relocs have to be done in combination with an R_M32R_LO16 reloc
because there is a carry from the LO16 to the HI16. Here we just save
the information we need; we do the actual relocation when we see the LO16.
This code is copied from the elf32-mips.c. We also support an arbitrary
number of HI16 relocs to be associated with a single LO16 reloc. The
assembler sorts the relocs to ensure each HI16 immediately precedes its
LO16. However if there are multiple copies, the assembler may not find
the real LO16 so it picks the first one it finds. */

There is some attempt to make this function usable for many architectures,
both for RELA and REL type relocs, if only to serve as a learning tool.
The RELOCATE_SECTION function is called by the new ELF backend linker
to handle the relocations for a section.
The relocs are always passed as Rela structures; if the section
actually uses Rel structures, the r_addend field will always be
zero.
This function is responsible for adjust the section contents as
necessary, and (if using Rela relocs and generating a
relocatable output file) adjusting the reloc addend as
necessary.
This function does not have to worry about setting the reloc
address or the reloc symbol index.
LOCAL_SYMS is a pointer to the swapped in local symbols.
LOCAL_SECTIONS is an array giving the section in the input file
corresponding to the st_shndx field of each local symbol.
The global hash table entry for the global symbols can be found
via elf_sym_hashes (input_bfd).
When generating relocatable output, this function must handle
STB_LOCAL/STT_SECTION symbols specially. The output symbol is
going to be the section symbol corresponding to the output
section, which means that the addend must be adjusted
accordingly. */
