This changes the semantics of `HLFHE.dot_eint_int` from memref-based
reference semantics to tensor-based value semantics. The former:
"HLFHE.dot_eint_int"(%arg0, %arg1, %arg2) :
(memref<Nx!HLFHE.eint<0>>, memref<Nxi32>, memref<!HLFHE.eint<0>>) -> ()
becomes:
"HLFHE.dot_eint_int"(%arg0, %arg1) :
(tensor<Nx!HLFHE.eint<0>>, tensor<Nxi32>) -> !HLFHE.eint<0>
As a side effect, data-flow analyses become much easier. With the
previous memref type of the plaintext argument it is difficult to
check whether the plaintext values are statically defined constants or
originate from a memory region changed at execution time (e.g., for
analyses evaluating the impact on noise). Changing the plaintext type
from `memref` to `vector` makes such analyses significantly easier.
-Encoding Cleartext to Plaintext Op
-Encoding Int to Plaintext Op
-Cleartext/Plaintext should add a bits field as `p`
-Op to create a constant Cleartext
-IntToCleartextOp: kind of casting an int to be later encoded, I'm not
sure if there is a better mechanism for this (e.g. auto casting in Ops),
but we currently need a way to encode int into plaintext, and we need to
go through cleartexts

This adds a new command line option
`--convert-hlfhe-tensor-ops-to-linalg` that invokes a conversion pass
replacing any HLFHE tensor operation with an appropriate instance of
`linalg.generic`.
Add a simple dot product between a vector of encrypted integers and a
vector of plaintext integers to the HLFHE dialect.
The operation takes two input operands and one output operand, all
modeled as memrefs. Example:
"HLFHE.dot_eint_int"(%lhs, %rhs, %out) :
(memref<?x!HLFHE.eint<0>>, memref<?xi32>, memref<!HLFHE.eint<0>>) -> ()
Make `HLFHE.EncryptedInteger` implement the
`MemRefElementTypeInterface` trait to allow the type to be used for
elements of memrefs.
The invocation of the `add_mlir_dialect` macro in
`include/zamalang/Dialect/HLFHE/IR/CMakeLists.txt` had to be broken
into its parts in order to pass `-typedefs-dialect=HLFHE` to
`mlir-tablegen`. This is required due to the inclusion of
`mlir/IR/BuiltinTypes.td` in
`include/zamalang/Dialect/HLFHE/IR/HLFHETypes.td`, resulting in
definitions from multiple dialects.
Add a small test actually using `HLFE.EncryptedInteger` in a `memref`.
