	* rs6000-tdep.c (IS_EFP_PSEUDOREG): Use correct constant for
	the EFP register set size.
	(efpr_pseudo_register_read): Use regcache_raw_read_part to read
	data from the VMX register.
	(efpr_pseudo_register_write): Use regcache_raw_write_part to read
	and write data from/to the VMX register.

gdb/testsuite/
	* gdb.arch/vsx-regs.exp: Add "vector_register1_vr" and
	"vector_register2_vr" test strings.  Test the extended floating
	point registers (F32~F63).
	* lib/gdb.exp (skip_vsx_tests): Update compile flags for the
	IBM XL C compiler.  Make the test program use a register provided
	by the compiler for the lxvd2x instruction.
