Expose mlir::parseType to bindings
Python bindings currently currently provide a makeScalarType function that
constructs one of the predefined types. It was implemented in the bindings
directly to circumvent the absence of standalone type parsing function. Now
that mlir::parseType has been made available, rely on the core parsing
procedure to construct types from strings in the bindings.
This changes includes a library reshuffling that splits out "CoreAPIs"

Allowing replacing non-root operations in DialectConversion.
When dealing with regions, or other patterns that need to generate temporary operations, it is useful to be able to replace other operations than the root op being matched. Before this PR, these operations would still be considered for legalization meaning that the conversion would either fail, erroneously need to mark these ops as legal, or add unnecessary patterns.

Fix linalg.subview behavior in (partially) static cases.
When the implementation of the strided memref [RFC](https://groups.google.com/a/tensorflow.org/forum/#!msg/mlir/MaL8m2nXuio/1scRqZa6AQAJ) landed, linalg started using this type instead of the now retired !linalg.view.
As static and partially static cases appear, the stride information needs to be maintained properly. In particular, the result type of the subview op was generally incorrect.
This CL fixes the issue by computing a return type that:
1. always has dynamic sizes, which is generally the only correct way to construct a subview in the absence of data padding and/or code versioning.
2. has the same strides as the base strided memref.
Point 1. above can be further refined but will needs further analysis and canonicalization to optimize the particular case where:
1. The base memref has static size along a given dimension.
2. The subview size can be statically derived (e.g. after canonicalization).
3. *And* the subview size is an even divisor of the base memref.
This 3rd constraint is well-known in the case of tiled layouts that don't assume implicit padding: the boundary tile may be only partial and has size given by `problem_size % tile_size`.
Tests are updated as appropriate.

Emit LLVM IR equivalent of sizeof when lowering alloc operations
Originally, the lowering of `alloc` operations has been computing the number of
bytes to allocate when lowering based on the properties of MLIR type. This does
not take into account type legalization that happens when compiling LLVM IR
down to target assembly. This legalization can widen the type, potentially
leading to out-of-bounds accesses to `alloc`ed data due to mismatches between
address computation that takes the widening into account and allocation that
does not. Use the LLVM IR's equivalent of `sizeof` to compute the number of
bytes to be allocated:
%0 = getelementptr %type* null, %indexType 0
%1 = ptrtoint %type* %0 to %indexType
