[PATCH, rs6000] Split up rs6000.c.

[PATCH, rs6000] Split up rs6000.c.

The source file rs6000.c has grown to unreasonable size and is being
split up into several smaller source files.  This should improve
compilation speed for building gcc.

This is the second of several patches to do this and moves most of the
function call and builtin code to a new source file.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions.  Is this ok for trunk?
