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.

Rahul Joshi ac54c5ccfa [XLA:GPU] Convert Cholesky custom call in XLA HLO to LHLO GPU Dialect. 
- Restructured LHLO GPU Cholesky to better match XLA HLO by eliminating the
  untyped buffer and changing is_upper attribute to is_lower.
- Change LhloDialectEmitter to emit LHLO GPU Cholesky operation.

Ben Vanik 1afada97ed Don't override MSVC CRT defaults. 
You can't mix CRT modes in binaries, so overriding these here breaks any build that links these files in that isn't also doing these same non-default overrides.

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.
