[PATCH] Externalize definition of create_tmp_reg_or_ssa_name

[Will Schmidt]

Hi,
    
I had initially posted this back in Dec, at which time it
was given an OK.  Since a bunch of time has passed, I'm reposting
to refresh memories, and ensure it's still OK.  :-)
    
I will be needing access to the create_tmp_reg_or_ssa_name()
function for some subsequent early expansion of vectors patches.
Thus...
    
Externalize the definition of create_tmp_reg_or_ssa_name
for use in rs6000.c.  (Usage will show up in later patches).
    
Bootstrapped and tested on powerpc64le-unknown-linux-gnu, and
powerpc-unknown-linux, (p7,p8le,p8be) with no regressions.
    
OK for trunk?
