Benjamin Kramer f4414fcd66 [MHLO:Linalg] Add support for lowering unsigned ops
This strips away the signedness with a type converter, using unrealized
conversion casts. The rest is mostly mechanically pushing the original op down
the pipeline so lowerings can see the original types.

Signed types stay signless for now. This can be changed in the HLO bridge later.

I did a pass over all ops and added unsigned lowerings where they were missing.
There may be more.

Currently the lowering will die at a later stage because it doesn't understand
the unrealized casts.

Adrian Kuegel 0e2b255f01 Lower LHLO::AbsOp to complex dialect.
Also fix the traits for LHLO::AbsOp to allow different types and add a
verifier.

Benjamin Kramer 240a44de82 [mhlo] Lower int->int cast to sign extension instead of zero extension
Signless does not mean unsigned here. Currently mhlo only has signed types.

Lei Zhang 39589add22 Use the correct shape when converting mhlo.reshape
If mhlo.reshape is not purely collapsing some consecutive operand
dimensions into result dimensions, we will generate two linalg
reshape op for it: the first one collapses all operand dimensions
into one dimension, and the second one expands it to all result
dimensions. For this case, the number of collapsed/expanded dimensions
should be coming strictly from the operand/result. It is different
from the case where we can generate one linalg reshape. For that case,
the reassociation map should have rank equal to the largest among
operand/result shape.

For integer operations, this lowers to a loop.

Adrian Kuegel 1f244c3e2c Fix SignOp lowering for floating point values.
It didn't return 0 for 0.0 and -0.0.
Currently we emit -0.0 for -0.0 which is correct according to the HLO dialect.
For the TF_SignOp we should emit 0.0 in that case, we will leave that as a TODO.
Enable the tests which work now, and add another one for Int64.
Also improve the registration code, we should not register the Int32 kernel.

Benjamin Kramer 3bf4277ea4 [MLIR] Add a lmhlo.reduce -> linalg.generic converter
Doesn't support tensors right now, as it's somewhat hairy to support both at
the same time. Since we use a generic lowering the result is messy
and needs a mem2reg pass to eliminate extra load/store/allocas.

…ad of std.store

The xla_lhlo.const lowering uses std.store to store a constant to
0-d memrefs. Update it to affine.store since such an access is trivially
affine (no indices). An affine.store can always be lowered to std.store.
