Is there a function that can be used to obtain a temporary hard

For what purpose?
If you need a scratch/temporary for reload, the way to get them is via
secondary reloads.
If you just need a scratch register for a pattern, you can allocate a
pseudo in an expander and clobber it in the pattern.
You can also use match_scratch. Though you might invite Vladimir's
wrath for doing that.
