Mahesh Ravishankar 44d0464d16 Use linalg.fill on tensors instead of tensor.generate in MHLO -> Linalg conversion.
linalg.fill on tensors is a structured op that allows use tile + fuse
to reduce the fill overhead.

Tres Popp ae722a883f Improve performance of lowered chlo.pow with integers
The new lowering takes 6 iterations of a loop always rather than iterating the exponent's number of times.

Hanhan Wang 30ce82790d Upstream mhlo.reduce lowering to Linalg to MHLO repo.
In IREE, we use indexed generic op to handle the initial value. However, we
lower it to a generic op that carries an init_tensor here, and leave the handle
of initialization problem to later passes.

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.

Benjamin Kramer f6b24a6d54 [mlir][hlo] Make min/max always propagate NaNs
This is the right behavior for TF and JAX and matches what TF does on GPU. It
doesn't match TF on CPU, but that's really a TF bug.

It was lowered to `sitofp` which resulted in `-1.0`.

Hanhan Wang 8f58f844e5 Upstream mhlo.dot lowering to Linalg to MHLO repo.
We prototyped the lowering from mhlo.dot to linalg.matmul in IREE. Since Linalg
now supports matmul in tensors world, we can move the lowering logic to tensors
world, and upstream to legalize_to_linalg.cc. The patch lowers the mhlo.dot to
the linalg.matmul/matvec/dot in tensors world.

Tres Popp a42213b870 Define lowering of [l]mhlo.pow.
For floating point operations, this uses std.pow.
For integer operations, this lowers to a loop.
This adds a dependency on scf.
