Fix to stop types failing for logical_xor during our fusions. 

* fix typo for add_sigmoid

Updated each source file in the repo with the existing license.

Fuse last instruction in fuse_pointwise
This is also fixes a bug with using an invalid iterator.

Currently, eliminate_contiguous will never remove contiguous for operators that use module inputs due to the fact that it doesn't pass the module inputs to compute_shape.

- Update to pass the module inputs correctly to compute_shape
- Fix the overloads of compute_shape so that when passed an empty vector of module inputs it will call the overload without module inputs
- Add tests with contiguous and pointwise module function.
- Move add_pointwise function to a seperate header to reuse across different tests

This enables the pointwise fusions using the MIGRAPHX_ENABLE_POINTWISE_FUSION env variable. Its disabled by default since MIOpen fusions need to be refactored.

This also adds a compile_ops pass to compile the pointwise modules. All tests except test_gpu_fast_math passes with MIGRAPHX_ENABLE_POINTWISE_FUSION=1 set.

Adds a pass to fuse pointwise operators into one "pointwsie" op that has a submodule which does the calculation.
