compiler: treat S("") as a string constant
The compiler neglected to notice that a conversion from a string
constant to a string type was a valid string constant.
No test case because this only caused a compiler failure when compiling
without optimization, which is not the normal case, and is not a case
that we test.
Fixes golang/go#56113
