adds elementwise opinfos and unary references, extends to out testing
This PR makes the following changes:
Prims:
- igamma and igammac are now correctly listed as elementwise binary operations, not elementwise unary operations
- elementwise prims now must specify their type promotion kind (this is currently unused)
Refs:
- complexhalf is now handled by opmath-style type promotion
- adds references for: abs, acos, acosh, asin, atan, ceil, cos, cosh, digamma, erf, erfinv, erfc, exp, expm1, isfinite, isnan, lgamma, log, log1p, neg, reciprocal, sign, sin, sinh, sqrt, square, tan, igamma, igammac
- adds "complex to float" and "bool to long" type promotion kinds
- updates out behavior to warn when resizing a non-empty tensor, consistent with current ops
- updates the elementwise unary reference template with type promotion
Tests:
- fixes torch.pow's OpInfo to correctly specify it only supports one scalar input, not two
- fixes elementwise binary reference inputs to not attempt generating certain tensors in complex half (for now, cc @kshitij12345)
- adds OpInfos for the following Python references: abs, acos, acosh, asin, atan, ceil, cos, cosh, digamma, erf, erfinv, erfc, exp, expm1, isfinite, isnan, lgamma, log, log1p, neg, reciprocal, round, sign, sin, sinh, sqrt, square, tan, atan2, bitwise_and, bitwise_left_shift, bitwise_or, bitwise_xor, eq, float_power, ge, gt, igamma, igammac, le, lt, maximum, minimum, mul, ne, nextafter, pow, sub, true_divide
