target-ppc: Correct VSX Integer to FP Conversion

This patch corrects the VSX integer to floating point conversion instructions
by using the endian correct accessors.  The auxiliary "j" index used by the
existing macros is now obsolete and is removed.  The JOFFSET preprocessor
macro is also obsolete and removed.
