TestMathBits: Call functions with original sample input values (#68947)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68947
`_test_math_view` currently calls the operator with different values
than those specified in the `SampleInput`. This is undesirable as it
could break mathematical properties required by the operator. Instead,
this calls `math_op_view(math_op_physical(sample.input))` to get a
view that represents the same value as the original input.
`test_neg_view` already did this by returning `torch._neg_view(-x)`
from `math_op_view` but this moves the handling into `_test_math_view`
to make it apply to all view op tests.
