khr@golang.org 1a0b86375f cmd/compile: remove redundant calls to cmpstring

The results of cmpstring are reuseable if the second call has the
same arguments and memory.

Note that this gets rid of cmpstring, but we still generate a
redundant </<= test and branch afterwards, because the compiler
doesn't know that cmpstring only ever returns -1,0,1.

Update #61725
