This patch contains all my fixes to ppc_register_u_addr to date; I
think it's complete and correct.
It combines a recent patch, "Compute u-area offsets of FP registers
correctly" with a change I committed to the ppc64-linux branch a while
back, and forgot to post. The patch I did post:

* ppc-linux-nat.c (ppc_register_u_addr): Correctly compute u-area
register offsets for both the 32- and 64-bit interfaces.
