CaiJingtao 2a3ed40449 Allow explicit size specifier for predicate operand of {sq, uq, }{incp, decp}
Omitting predicate size specifier in vector form of {sq, uq, }{decp, incp} is deprecated and will be prohibited in a future release of the aarch64,
see https://developer.arm.com/documentation/ddi0602/2021-09/SVE-Instructions/DECP--vector---Decrement-vector-by-count-of-true-predicate-elements-.

This allows explicit size specifier, e.g. `decp z0.h, p0.h`, for predicate operand of these SVE instructions.
The existing behaviour of not requiring the specifier is preserved.
And the disasembly is with the specifier with this patch.

The GAS tests passed under our local tests.

opcodes/
	* aarch64-asm.c: Modify `sve_size_hsd` encoding.
	* aarch64-tbl.h (aarch64_opcode_table): Add QUALS's type OP_SVE_Vv_HSD
	for decp, incp, sqdecp, sqincp, uqdecp and uqincp.

gas/
	* testsuite/gas/aarch64/sve-movprfx_23.s: Update movprfx_23 testcase's
	test_sametwo macro, where take the predicate size specifier.
	* testsuite/gas/aarch64/sve-movprfx_23.d: Update movprfx_23 testcase's
	expected disassembly.
	* testsuite/gas/aarch64/sve-movprfx_23.l: Update movprfx_23 testcase's
	expected assembler messages.
	* testsuite/gas/aarch64/sve.s: Add sve testcase's instructions for
	decp, incp, sqdecp, sqincp, uqdecp and uqincp, which take the
	predicate size specifier.
	* testsuite/gas/aarch64/sve.d: Update sve testcase's expected
	disassembly.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
