Revert "Fix lit test failures in CodeGenCoroutines"

This reverts commit 63fff0f5.

When targeting a specific CPU with scalable vectorization, the knowledge
of that particular CPU's vscale value can be used to tune the cost-model
and make the cost per lane less pessimistic.

If the target implements 'TTI.getVScaleForTuning()', the cost-per-lane
is calculated as:

  Cost / (VScaleForTuning * VF.KnownMinLanes)

Otherwise, it assumes a value of 1 meaning that the behavior
is unchanged and calculated as:

  Cost / VF.KnownMinLanes

Use ComputeMinSignedBits() to ensure the mul source operands at least sign-extend down from the bottom 16 bits.

This will make it easier if/when we try to support handling of source types larger than 32-bits.

The common use case for calling createStepForVF is currently something
like:

  Value *Step = createStepForVF(Builder, ConstantInt::get(Ty, UF), VF);

and it makes more sense to reduce overall lines of code and change the
function to let it create the constant instead. With my patch this
becomes:

  Value *Step = createStepForVF(Builder, Ty, VF, UF);

and the ConstantInt is created instead createStepForVF. A side-effect of
this is that the code in createStepForVF is also becomes simpler.

As part of this patch I've also replaced some calls to getRuntimeVF
with calls to createStepForVF, i.e.

  getRuntimeVF(Builder, Count->getType(), VFactor * UFactor) ->
  createStepForVF(Builder, Count->getType(), VFactor, UFactor)

because this feels semantically better.

When inserting an unpacked FP subvector into a packed vector we
can simply cast the unpacked value into a packed value, since
both types are legal for SVE. We can then use this as the input

The revision updates the packing loop search in hoist padding. Instead of considering all loops in the backward slice, we now compute a separate backward slice containing the index computations only. This modification ensures we do not add packing loops that are not used to index the packed buffer due to spurious dependencies. One instance where such spurious dependencies can appear is the extract slice operation introduced between the tile loops of a double tiling.
