Richard Henderson f6bcc5b8f9 target/ppc: Improve helper_dcbz for user-only 
Mark the reserve_addr check unlikely.  Use tlb_vaddr_to_host
instead of probe_write, relying on the memset itself to test
for page writability.  Use set/clear_helper_retaddr so that
we can properly unwind on segfault.

With this, a trivial loop around guest memset will no longer
spend nearly 25% of runtime within page_get_flags.
