Power10 VSX 32-byte storage access

bfd/
	* elf64-ppc.c (xlate_pcrel_opt): Handle lxvp and stxvp.
opcodes/
	* ppc-opc.c (insert_xtp, extract_xtp): New functions.
	(XTP, DQXP, DQXP_MASK): Define.
	(powerpc_opcodes): Add lxvp, stxvp, lxvpx, stxvpx.
	(prefix_opcodes): Add plxvp and pstxvp.
gas/
	* testsuite/gas/ppc/vsx_32byte.d,
	* testsuite/gas/ppc/vsx_32byte.s: New test.
	* testsuite/gas/ppc/ppc.exp: Run it.
ld/
	* testsuite/ld-powerpc/pcrelopt.s: Add lxvp and stxvp.
	* testsuite/ld-powerpc/pcrelopt.d: Update.
