[PATCH 54/57][Arm][OBJDUMP] Add support for MVE instructions: vmax(a), vmax(a)v, vmaxnm(a), vmaxnm(a)v, vmin(a), vmin(a)v, vminnm(a), vminnm(a)v and vmla

opcodes/ChangeLog:
2019-05-16  Andre Vieira  <andre.simoesdiasvieira@arm.com>
	    Michael Collison <michael.collison@arm.com>

	* arm-dis.c (thumb32_opcodes): Add new instructions.
	(enum mve_instructions): Likewise.
	(is_mve_encoding_conflict): Likewise.
	(is_mve_unpredictable): Likewise.
	(print_mve_size): Likewise.
