[mlir] Refactor ElementsAttr's value access API
There are several aspects of the API that either aren't easy to use, or are
deceptively easy to do the wrong thing. The main change of this commit
is to remove all of the `getValue<T>`/`getFlatValue<T>` from ElementsAttr
and instead provide operator[] methods on the ranges returned by
`getValues<T>`. This provides a much more convenient API for the value
ranges. It also removes the easy-to-be-inefficient nature of
getValue/getFlatValue, which under the hood would construct a new range for
the type `T`. Constructing a range is not necessarily cheap in all cases, and
could lead to very poor performance if used within a loop; i.e. if you were to
naively write something like:
```
DenseElementsAttr attr = ...;
for (int i = 0; i < size; ++i) {
// We are internally rebuilding the APFloat value range on each iteration!!
APFloat it = attr.getFlatValue<APFloat>(i);
}

[flang] Don't reference non-invariant symbols in shape expressions
When an array's shape involves references to symbols that are not
invariant in a scope -- the classic example being a dummy array
with an explicit shape involving other dummy arguments -- the
compiler was creating shape expressions that referenced those
symbols. This might be valid if those symbols are somehow
captured and copied at each entry point to a subprogram, and
the copies referenced in the shapes instead, but that's not
the case.
This patch introduces a new expression predicate IsScopeInvariantExpr(),
which defines a class of expressions that contains constant expressions
(in the sense that the standard uses that term) as well as references
to items that may be safely accessed in a context-free way throughout
their scopes. This includes dummy arguments that are INTENT(IN)
and not VALUE, descriptor inquiries into descriptors that cannot
change, and bare LEN type parameters within the definitions of
derived types. The new predicate is then used in shape analysis

[NFC][LoopVectorize] Make the createStepForVF interface more caller-friendly
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.
