Hello!

While looking at recent Andi's atomic patches, I noticed that memory
model operand is not properly masked in a couple of i386 sync.md
patterns.

2013-01-13  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/sync.md (mem_thread_fence): Mask operands[0] with
	MEMMODEL_MASK to determine memory model.
	(atomic_store<mode>): Ditto from operands[2].
	* config/i386/i386.c (ix86_memmodel_check): Declare "strong" as bool.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN as obvious.

The patch will be also committed to 4.7 branch.

Uros.
