IntrWriteArgMem implies nocapture, but this wasn't
taken advantage of anywhere. Change the definition
of IntrWriteArgMem to no longer imply nocapture, and
explicitly add nocapture attributes everywhere (well,
not quite everywhere, because some of these intrinsics
did capture their arguments!). Also, make clear that
the lack of other side-effects does not exclude doing
volatile loads or stores - the atomic intrinsics do
these, yet they are all marked IntrWriteArgMem (this
change is safe because nothing exploited it).

BasicAA was making the assumption that a local allocation which hadn't escaped

Teach IndVarSimplify to optimize code using the C "int" type for
loop induction on LP64 targets. When the induction variable is
used in addressing, IndVars now is usually able to inserst a
64-bit induction variable and eliminates the sign-extending cast.
This is also useful for code using C "short" types for
induction variables on targets with 32-bit addressing.
Inserting a wider induction variable is easy; the tricky part is
determining when trunc(sext(i)) expressions are no-ops. This
requires range analysis of the loop trip count. A common case is
when the original loop iteration starts at 0 and exits when the
induction variable is signed-less-than a fixed value; this case
is now handled.
This replaces IndVarSimplify's OptimizeCanonicalIVType. It was
doing the same optimization, but it was limited to loops with
constant trip counts, because it was running after the loop
rewrite, and the information about the original induction
variable is lost by that point.
Rename ScalarEvolution's executesAtLeastOnce to
isLoopGuardedByCond, generalize it to be able to test for
ICMP_NE conditions, and move it to be a public function so that
IndVars can use it.
