Instead use either Type::getPointerElementType() or
Type::getNonOpaquePointerElementType().
This is part of D117885, in preparation for deprecating the API.
The HexagonVectorCombine pass was moving an instruction
incorrectly, which caused a use in a GEP that was not yet
defined.
HexagonVectorCombine removes a load from a group due to its
dependences, but in realignGroup, the load is processed anyways.
In realignGroup, when determining the maximum alignment, only
those instructions still in the group should be considered.
Most changes are rewording comments but there are some assertions that I rephrased.

Stop using APInt constructors and methods that were soft-deprecated in
D109483. This fixes all the uses I found in llvm, except for the APInt
unit tests which should still test the deprecated methods.

The code was using getTypeStoreSize to calculate the difference
between consecutive objects. The calculation was incorrect due
to padding that is added between consecutive objects. The
getTypeAllocSize includes the padding amount. For example,
if the type is [19 x i8], the difference between consecutive
objects is 32 bytes, not 19 bytes.
A second case for getTypeAllocSize is needed when computing
the pointer values for the vector accesses. The calculation needs
to account for the padding as well.

Same as other CreateLoad-style APIs, these need an explicit type
argument to support opaque pointers.

Passing template parameter packs to std::map doesn't work in VS 2017/2019, so this updates the preprocessor version check to use an alternate version in VS2019, as well.

The Hexagon Vector Combine pass genertes stores for a complete
aligned vector. The start of each section is a multiple of the
vector size, so that value is passed to normalize to compute
the offset of the stores in the section. The first store may
not occur at offset 0 when there is a gap between sections.
As mentioned in D93793, there are quite a few places where unary `IRBuilder::CreateShuffleVector(X, Mask)` can be used
instead of `IRBuilder::CreateShuffleVector(X, Undef, Mask)`.
Let's update them.
Actually, it would have been more natural if the patches were made in this order:
(1) let them use unary CreateShuffleVector first
(2) update IRBuilder::CreateShuffleVector to use poison as a placeholder value (D93793)
The order is swapped, but in terms of correctness it is still fine.

The version in the path, 14.23, corresponds to _MSC_VER 1923, so raise
the version floor to 1924.
I have not tested with versions between 1924 and 1928 (latest), but the
latest works with the variadic version.
The getPayload/getMask/getPassThrough functions should return values
that could be composed into a masked load/store without any additional
type casts. The previous fix violated that.
Instead, convert scalar mask to a vector right before rescaling.
AlignVectors treats all loaded/stored values as vectors of bytes,
and masks as corresponding vectors of booleans, so make getMask
produce a 1-element vector for scalars from the start.
