[ConstProp] Remove ConstantPropagation

As discussed in
http://lists.llvm.org/pipermail/llvm-dev/2020-July/143801.html.

Currently no users outside of unit tests.

Replace all instances in tests of -constprop with -instsimplify.
Notable changes in tests:
* vscale.ll - @llvm.sadd.sat.nxv16i8 is evaluated by instsimplify, use a fake intrinsic instead
* InsertElement.ll - insertelement undef is removed by instsimplify in @insertelement_undef
llvm/test/Transforms/ConstProp moved to llvm/test/Transforms/InstSimplify/ConstProp

Now that we have the standard run-of-the-mill argument types out of the way,
lets get a little wild and crazy. Lets say that we want our optimizer to accept
a **list** of optimizations to perform, allowing duplicates. For example, we
might want to run: "``compiler -dce -constprop -inline -dce -strip``". In this
might want to run: "``compiler -dce -instsimplify -inline -dce -strip``". In this
case, the order of the arguments and the number of appearances is very
important. This is what the "``cl::list``" template is for. First, start by
defining an enum of the optimizations that you would like to perform:

``-constprop``: Simple constant propagation
-------------------------------------------
This pass implements constant propagation and merging. It looks for
instructions involving only constant operands and replaces them with a constant
value instead of an instruction. For example:
.. code-block:: llvm
add i32 1, 2
becomes
.. code-block:: llvm
i32 3
NOTE: this pass has a habit of making definitions be dead. It is a good idea
to run a :ref:`Dead Instruction Elimination <passes-die>` pass sometime after
running this pass.
