Use new registers for the output, so that we never overlap
the input address, which could happen for user-only.
This avoids a "tmp = addr + 0" in that case.

Direct branch patching was disabled when using TCG_REG_TB in commit
736a1588 ("tcg/ppc: Fix race in goto_tb implementation").

The issue with direct branch patching with TCG_REG_TB is the lack of
synchronization between the new TCG_REG_TB being established and the
direct branch being patched in.

If each translation block is responsible for establishing its own
TCG_REG_TB then there can be no synchronization issue.

Make each translation block begin by setting up its own TCG_REG_TB.
Use the preferred 'bcl 20,31,$+4' sequence.
