We did not want these inlined on sparc64 for a good reason.
The pointer arithmatic gets expanded to many additions,
subtractions, and shifts, and I felt it too much to inline.
If you want to consolidate all of the implementations, that's
fine, but please keep the option of not inlining these two
routines.
Thank you.
