inconsistency of reflect.SliceHeader's field types with official reflect package

[mathetake]

When I was working with reflect.SliceHeader of TinyGo, I found that the type of SliceHeader.{Len,Cap} is uintptr and is different from the one of Go's official implementation which is int:

• tinygo:

  tinygo/src/reflect/value.go

  Lines 695 to 696 in 720a54a

  	Len uintptr
  	Cap uintptr

• go: https://github.com/golang/go/blob/3dec253783e1211989102ac6abd34cddbf8ba0e6/src/reflect/value.go#L1982-L1983

is this intentional? If not, may I fix this and replace uintptr with int ?

motivation: If possible, I do not want to have separated files for Go (for testing) and Tinygo (for building) of virtually identical files
