Hi,

This patch replaces "BB [%i]" with "[bb %i]" in vzeroupper RTL dump so
that it is consistent with other basic block dump. One can search
"bb XX" in vzeroupper RTL dump.

I am checking it in.

	* config/i386/i386.c (move_or_delete_vzeroupper_2): Replace
	"BB [%i]" with "[bb %i]" in dump.
	(move_or_delete_vzeroupper_1): Likewise.
	(rescan_move_or_delete_vzeroupper): Likewise.  Always dump
	upper 128bit state at exit.
