PowerPC disassembly of pcrel references
This adds some annotation to Power10 pcrel instructions, displaying
the target address (ie. pc + D34 field) plus a symbol if there is one
at exactly that target address. pld from the .got or .plt will also
look up the entry and display it, symbolically if there is a dynamic
relocation on the entry.
include/
* dis-asm.h (struct disassemble_info): Add dynrelbuf and dynrelcount.
binutils/
* objdump.c (struct objdump_disasm_info): Delete dynrelbuf and
dynrelcount.
(find_symbol_for_address): Adjust for dynrelbuf and dynrelcount move.
(disassemble_section, disassemble_data): Likewise.
opcodes/
* ppc-dis.c (struct dis_private): Add "special".
(POWERPC_DIALECT): Delete. Replace uses with..
(private_data): ..this. New inline function.
(disassemble_init_powerpc): Init "special" names.
(skip_optional_operands): Add is_pcrel arg, set when detecting R
field of prefix instructions.
(bsearch_reloc, print_got_plt): New functions.
(print_insn_powerpc): For pcrel instructions, print target address
and symbol if known, and decode plt and got loads too.

* testsuite/gas/ppc/prefix-pcrel.d: Update expected output.
* testsuite/gas/ppc/prefix-reloc.d: Likewise.
