s390.md: Add "bcr_flush" value to mnemonic attribute. 

2013-09-06  Andreas Krebbel  <Andreas.Krebbel@de.ibm.com>

	* config/s390/s390.md: Add "bcr_flush" value to mnemonic
	attribute.
	("mem_thread_fence_1"): Use bcr 14,0 for z196 and later.
	Set the mnemonic attribute to "bcr_flush".  Set the "z196prop"
	attribute to "z196_alone".
	* config/s390/2827.md: Add "bcr_flush" to "ooo_groupalone" and
	"zEC12_simple".
