[PATCH]: Power7 changes, part 2, add VSX registers, bswap*, address support, debugging


This is patch #2 for my power7 changes, and it assumes patch #1 has been
applied.  It is checked in as subversion id #148683, which is based on mainline
subversion id #148616.  The branch is:
branch svn+ssh://@gcc.gnu.org/svn/gcc/branches/ibm/power7-tmp

This patch does the following:

1) Flesh out the -mdebug=addr and -mdebug=cost options.

2) Restrict vector addresses which must be reg+reg on Altivec and VSX somewhat
   earlier, but allow addresses with offsets based on the virtual stack
   pointers, until the VSP's are resolved.

3) Add the VSX_REGS register class, which overlays on top of the traditional
   floating point registers and the altivec registers.  VSX_REGS is not used in
   any insn in this patch set.

4) Add support for 16/64 bit memory swap operations.
