Cherry Mui 50a8b3a30e hash/maphash, cmd/compile: make Comparable[string] not escape its argument 
Currently, maphash.Comparable forces its argument to escape if it
contains a pointer, as we cannot hash stack pointers, which will
change when the stack moves. However, for a string, it is actually
okay if its data pointer points to the stack, as the hash depends
on only the content, not the pointer.

Currently there is no way to write this type-dependent escape
logic in Go code. So we implement it in the compiler as an
intrinsic. The compiler can also recognize not just the string
type, but types whose pointers are all string pointers, and make
them not escape.

Fixes #70560.
