[PATCH, rs6000] Split up rs6000.c

Programming / Compilers / GCC - seurer [138bc75d-0d04-0410-961f-82ee72b054a4] - 25 June 2019 20:06 EDT

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 first of several patches to do this and moves most of the prologue/epilogue 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?
