Add tuned powerpc assembler written by IBM and released under a 3-clause
BSD Lisc as part of the perflib project.
http://sourceforge.net/projects/ppcperflib/

Tested the new functions with microbenchmarks on a number of different
CPU types, and found that most cpus either benefited greatly, or were
unaffected. Primarily G4 CPU's were unaffected, and all others showed
speedups. My 7044 (POWER3) went from a 70.6 to a 73.2 (thats good) in
bytebench with a complete release built with these. Also passed
regression tests.

branches: 1.5.48;
Use END(foo) everywhere.
Make __cerror hidden.
Use non-PLT calls to __cerror.
Use assym.h when appropriate.
Use addi to adjust stack instead of loading it.
Add __RCSIDs
Force -D_NOREGNAMES for all .S files.
[this is all in preperation for secure plt support]

revert

And yet more .S files...

Fix PR 32363 by defining _NOREGNAMES.

Someone should complete the transition.

Merge libkern + libc common files. As requested by core.

Including assym.h is not needed and will break the build, because it does not
exist that early. Deleted it.
