<rdar://problem/7352605>. When building schedule graph use mayAlias information to avoid chaining loads/stores of spill slots with non-aliased memory ops.

functions that don't have local linkage.  Basically, we need to be more
careful about propagating argument information to functions whose results
we aren't tracking.  This fixes a miscompilation of 
LLVMCConfigurationEmitter.cpp when built with an llvm-gcc that has ipsccp
enabled.

This makes both logical sense (see below) and increases the
number of functions marked readnone/readonly by about 1-2%
in practice.  The number of functions marked nocapture goes
up by about 5-10%.  The reason it makes sense is shown by
the following example: if you run -functionattrs -inline on
it, then no attributes are assigned.  But if you instead run
-inline -functionattrs then @f is marked readnone because the
simplifications produced by the inliner eliminate the store.

@x = external global i32

define void @w(i1 %b) {
        br i1 %b, label %write, label %return
write:
        store i32 1, i32 *@x
        br label %return
return:
        ret void
}

define void @f() {
        call void @w(i1 0)
        ret void
}
