This is a fun one: I just sent go.dev/cl/790740, which elides method wrappers for embedded types at offset zero, common for mixins/inherited data types. Doing this removes 60 _thousand_ method wrappers from tsgo's AST package, dropping the compilation of our main exe from 49s to 28s on my machine.

It also shaves 1.3% off of the cmd/compile binary as it also uses embedding in the same way tsgo does for its AST/types (and, probably will even more in the future if I'm able to find time) In addition, 0.6% off of go, 0.66% off of pprof. This is more or less a "fix" for github.com/golang/go/is...

Frankly I'm shocked this worked on the first try, with just one tweak, disabling it in linkshared mode (yay relative relocs) Here's to hoping I haven't missed anything, but trybots are happy, so......

To be clear, this all is about this pattern: type E struct{ x int } func (e *E) M() int { return e.x } type T struct { E; y int } You don't need any special wrapper / adapter for this because it's a pointer. Can't do this for value receivers, since you need to be able to "call" with T.

Also, this shaves 1.44MB off of tsgo, which is both amazing, and also exactly one floppy disk of data
