Changes: 1) pytorch#17527 changed dispatch macros to be ScalarType based instead of at::Type based. This broke cpp extensions that relied on dispatch macros. Since IMO these should be ScalarType based, we allow either at::Type or at::ScalarType to be passed, but passing at::Type will result in a deprecated warning. 2) Reintroduce macros that were deleted (AT_DISPATCH_ALL_TYPES_AND_HALF, AT_DISPATCH_COMPLEX_TYPES, AT_DISPATCH_ALL_TYPES_AND_HALF_AND_COMPLEX, AT_DISPATCH_ALL_TYPES_AND_COMPLEX); the AND_HALF ones now give a deprecated warning because there are more extensible macros that were introduced in their place. 3) Makes AT_DISPATCH_ALL_TYPES_AND_COMPLEX_AND into a ScalarType based macro (and updates usages). This was the result of a logical merge conflicts.

i'm curious whether these empty functions will be optimized out, and if so will the deprecation warning still be emitted? although if that's the case, there's probably not an easy way around that.

The warning is suppose to be emitted at compile-time, so a compiler should be able to emit them regardless of the optimization.

Summary: Changes: 1) pytorch/pytorch#17527 changed dispatch macros to be ScalarType based instead of at::Type based. This broke cpp extensions that relied on dispatch macros. Since IMO these should be ScalarType based (and some extensions have already updated), we allow either at::Type or at::ScalarType to be passed, but passing at::Type will result in a deprecated warning. 2) Reintroduce macros that were deleted (AT_DISPATCH_ALL_TYPES_AND_HALF, AT_DISPATCH_COMPLEX_TYPES, AT_DISPATCH_ALL_TYPES_AND_HALF_AND_COMPLEX, AT_DISPATCH_ALL_TYPES_AND_COMPLEX); the AND_HALF ones now give a deprecated warning because there are more extensible macros that were introduced in their place. 3) Makes AT_DISPATCH_ALL_TYPES_AND_COMPLEX_AND into a ScalarType based macro (and updates usages). This was the result of a logical merge conflicts. 4) Adds a new macro, C10_DEPRECATED_MESSAGE for passing a deprecated message to the compiler. I didn't spend much time seeing if this can be enabled for versions before C++14.
