epiphany/disassembler: Improve alignment of output.

Browse source 
Always set the bytes_per_line field (of struct disassemble_info) to the
same constant value, this is inline with the advice contained within
include/dis-asm.h.

Setting this field to a constant value will cause the disassembler
output to be better aligned.

cpu/ChangeLog:

	* epiphany.opc (epiphany_print_insn): Set info->bytes_per_line to
	a constant to better align disassembler output.

opcodes/ChangeLog:

	* epiphany-dis.c: Regenerated from latest cpu files.

gas/ChangeLog:

	* testsuite/gas/epiphany/sample.d: Update expected output.
