Arthur Eubanks d74ec65308 [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

; This testcase checks to make sure that the assembler can handle floating
; point constants in IEEE hex format. This also checks that the disassembler,
; when presented with a FP constant that cannot be represented exactly in
; exponential form, outputs it correctly in hex format. This is a distillation
; of the bug that was causing the Olden Health benchmark to output incorrect
; results!
