Duncan Sands 674fdc9a28 Run the functionattrs pass after the inliner, and not before. 
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
}
