2020-01-02compiler, runtime, reflect: generate hash functions only for map keysIan Lance Taylor18-385/+421
Right now we generate hash functions for all types, just in case they are used as map keys. That's a lot of wasted effort and binary size for types which will never be used as a map key. Instead, generate hash functions only for types that we know are map keys. Just doing that is a bit too simple, since maps with an interface type as a key might have to hash any concrete key type that implements that interface. So for that case, implement hashing of such types at runtime (instead of with generated code). It will be slower, but only for maps with interface types as keys, and maybe only a bit slower as the aeshash time probably dominates the dispatch time. Reorg where we keep the equals and hash functions. Move the hash function from the key type to the map type, saving a field in every non-map type. That leaves only one function in the alg structure, so get rid of that and just keep the equal function in the type descriptor itself. While we're here, reorganize the rtype struct to more closely match the gc version. This is the gofrontend version of https://golang.org/cl/191198.

2020-01-02compiler: split writing of equal and hash functions for typesIan Lance Taylor7-361/+545
Separate the generation of type equality and hash functions, rather than doing them in a single operation. This is almost entirely a pure refactoring in preparation for generating hash functions only for types that are map keys. The only change in generated code is that for types that are the size of numeric types, but not aligned like numeric types, such as [8]byte, now use standard hash functions. They previously used special-purpose hash functions because they required special-purpose equal functions. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/212842 From-SVN: r279847
