thomasraoux 3fc0fbefc8 [mlir][vector] Move transferOp on tensor opt to folder/canonicalization 
Move the existing optimization for transfer op on tensor to folder and
canonicalization. This handles the write after write case and read after write
and also add write after read case.

Matthias Springer 95f8135043 [mlir] Change vector.transfer_read/write "masked" attribute to "in_bounds". 
This is in preparation for adding a new "mask" operand. The existing "masked" attribute was used to specify dimensions that may be out-of-bounds. Such transfers can be lowered to masked load/stores. The new "in_bounds" attribute is used to specify dimensions that are guaranteed to be within bounds. (Semantics is inverted.)

Thomas Raoux 26c8f9081b [mlir[[vector] Extend Transfer read/write ops to support tensor types. 
Transfer_ops can now work on both buffers and tensor. Right now, lowering of
the tensor case is not supported yet.

Christian Sigg 0bf4a82a5a [mlir] Use mlir::OpState::operator->() to get to methods of mlir::Operation. This is a preparation step to remove the corresponding methods from OpState.

River Riddle e66c2e259f [mlir][NFC] Remove Function.h and Module.h in favor of BuiltinOps.h 
The definitions of ModuleOp and FuncOp are now within BuiltinOps.h, making the individual files obsolete.

Thomas Raoux 369c51a74b [mlir][vector] Add transfer_op LoadToStore forwarding and deadStore optimizations 
Add transformation to be able to forward transfer_write into transfer_read
operation and to be able to remove dead transfer_write when a transfer_write is
overwritten before being read.
