Smit Hinsu b016b5a219 Fix constant folding of mhlo.convert op with i1 element types
Boolean element values should be fetched as an unsigned integer and not signed integer which would return -1 for true.

Added to a TODO to handle unsigned types correctly as well as we don't seem to be using unsigned types.

Ben Vanik 88a5bde51f Fixing M_PI compile error on MSVC.
M_PI and other math constants (used in chlo_legalize_hlo_patterns.td)
are not part of the C++ standard and must be enabled on MSVC
(similar to _GNU_SOURCE adding glibc symbols to posix headers).

Tres Popp 1dffa62fe9 Fold away shape.shape_of(mhlo.dynamic_reshape(inp, shape))
This specific pattern can be replaced with the shape
passed to dynamic_reshape. This is implemented as a

Alexander Belyaev d4f2c767d3 [HLO] Fix HLO DynamicBroadcastInDimOp -> LHLO lowering.
The conversion had a bug in computation of strides and sizes args for std.memref_reinterpret_cast. The previous version also relied on linalg::ReshapeOp to do broadcasting when the rank of the output was higher than the rank of the input. Now the broadcasting is entirely done via descriptor modification and linalg::ReshapeOp was replaced with CopyOp.

* Fix assumption of ranked shape in GetDimensionSize op.

Robert Suderman a926e0f040 Removed Op(Complex, Real) lowering to address complex type inference issue
Lowerings that depended on operations between real and complex types may
not infer the correct intermediate type. Removing these operations as

Richard Uhler 82031b356c Improve error message for improperly shaped slice indices.
The slice indices must be rank-1 and have the same number of elements of the
rank of the operand. Give reasonable error messages for violations of these
requirements instead of a misleading error message that the types of the
indices don't all match.
