Stop "objdump -d" from disassembling past a symbolic address.

include	* dis-asm.h (struct disassemble_info): Add stop_vma field.

binuti  * objdump.c (disassemble_bytes): Set the stop_vma field in the
	disassemble_info structure when disassembling code sections with
	-d.
	* doc/binutils.texi (objdump): Document the discrepancy between -d
	and -D.

opcodes	* dis-buf.c (buffer_read_memory): Fail is stop_vma is set and the
	requested region lies beyond it.
	* bfin-dis.c (print_insn_bfin): Ignore sysop instructions when
	looking for 32-bit insns.
	* mcore-dis.c (print_insn_mcore): Disable stop_vma when reading
	data.
	* sh-dis.c (print_insn_sh): Likewise.
	* tic6x-dis.c (print_insn_tic6x): Disable stop_vma when reading
	blocks of instructions.
	* vax-dis.c (print_insn_vax): Check that the requested address
	does not clash with the stop_vma.

tests	* gas/arm/backslash-at.s: Add extra .byte directives so that the
	foo symbol does not appear to point half way through an
	instruction.
	* gas/arm/backslash-at.d: Update expected disassembly.
	* gas/i386/ilp32/x86-64-opcode-inval-intel.d: Likewise.
	* gas/i386/ilp32/x86-64-opcode-inval.d: Likewise.
	* gas/i386/x86-64-opcode-inval-intel.d: Likewise.
	* gas/i386/x86-64-opcode-inval.d: Likewise.
