The alloc->insert/compress->load chain needs to be
properly represented with an SSA chain now in loops
and if statements to properly reflect the modifying
behavior (runtime support lib is forgiving on breaking
this, but the new codegen is not).

The indices for insert/compress were previously provided as
a memref<?xindex> with proper rank, since that matched the
argument for the runtime support libary better. However, with
proper codegen coming, providing the indices as SSA values
is much cleaner. This also brings the sparse_tensor.insert
closer to unification with tensor.insert, planned in the
longer run.

This change goes not impact any semantics yet, but it
is in preparation for implementing the unordered and not-unique
properties. Changing lex_insert to insert is a first step.

The "sparsification" pass does not need the ability to use runtime values for
the dimension, so the only source for variability would have been user code.
Restricting the dimension to constants simplifies code generation.

This fixes all sorts of ABI issues due to passing by-value
(using by-reference with memref's exclusively).

Now that we have an AllocTensorOp (previously InitTensorOp) in the bufferization dialect, the InitOp in the sparse dialect is no longer needed.

This revision adds support for the linalg.index to the sparse compiler
pipeline. In essence, this adds the ability to refer to indices in
the tensor index expression, as illustrated below:
Y[i, j, k, l, m] = T[i, j, k, l, m] * i * j
