[PATCH] Externalize definition of create_tmp_reg_or_ssa_name

[Will Schmidt <will_schmidt@vnet.ibm.com>]

Hi,

For some future rs6000 vector folding patches, I will be needing
access to the create_tmp_reg_or_ssa_name() function in rs6000.c.
Thus...
Externalize the definition of create_tmp_reg_or_ssa_name
for use in rs6000.c.  The actual usage will show up in later patches.

I'll note that I do not have any 'usage' patches quite ready to go, so
I may just sit on committing this until one of those usage patches is ready.

I've bootstrapped and make check with this patch applied in conjunction with
other patches. 

OK for trunk?
