b532816ac9 Describe invoke instruction dependencies. Generalize the text for 
terminator instructions so that it applies to all terminators with
multiple successors, including invoke.

855abed3cb Say "operations" instead of "instructions", as nsw can be applied to 
constant expressions as well as instructions.

57b6e9eb6c Remove the -enable-sjlj-eh option, which doesn't do anything. 
Remove the -enable-eh option which is only used by the JIT,
and replace it with -jit-enable-eh.

34b3d993e4 Rewrite the section on trap values to contain a generic description 
of dependence and define trap values in terms of dependence, instead
of trying to cover the concept with a flurry of ad-hoc rules.

The dependence model isn't complete yet, but it's already much more
rigorous than the description it replaces.

fff6c5332f Add an initial description of a new concept: trap values, and change 
the definition of the nsw and nuw flags to make use of it.

nsw was introduced to help optimizers answer yes to the following:

  // Can we change i from i32 to i64 to eliminate the cast inside the loop?
  for (int i = 0; i < n; ++i) A[i] *= 0.1;

  // Can we assume that this loop will eventually terminate?
  for (int i = 0; i <= n; ++i) A[i] *= 0.1;

In its current form, it isn't truly sufficient for either.

In the first case, if the increment overflows, it'll still have some
valid i32 value; sign-extending it will produce a value which is 33
homogeneous sign bits trailed by 31 independent undef bits. If i is
promoted to i64, it won't have those same values when it reaches that
point. (The compiler could recover here by reasoning about how i is
used by the load, but that's a lot more complicated and isn't always
possible.)

In the second case, there is no value for i which will be greater than
n, so having the increment return undef on overflow doesn't help.

Trap values are a formalization of some existing concepts that we have
about LLVM IR, and give the optimizers a better basis for answering yes
to both questions above.

7e7ae5ad69 Refer to -help instead of --help since this is what tools themselves say. 
Also, have tools output -help-hidden rather than refer to --help-hidden,
for consistency, and likewise adjust documentation.  This doesn't change
every mention of --help, only those which seemed clearly safe.
