fix an IPSCCP bug I introduced when I changed IPSCCP to start working on
...
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.

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
}
