Chris Lattner 2d51a4ce8f remove some old hacky code that tried to infer whether a store
occured in a pattern, but failed miserably.  The new code works for
any instruction that has a store in its pattern, including all the 
x86 mem op mem instructions.

The only target-independent code that uses this is branch folding,
so this won't change anything in practice.
