string Enums doesn't work as keys for AA's

[Kozzi11]

module main;
import std.stdio;

enum E : string
{
A = "A",
B = "B",
C = "C",
}

void main(string[] args)
{
string[E] aa = [E.A : "a", E.B : "b", E.C : "c"];
foreach(val; aa)
{
writeln(val);
}
}

ldc output:
Error: Integer constant expression expected instead of "A"

I can reproduce it. Thanks for the report.

It looks like that we try to create an integer from an array of chars. LLVM doesn't like that. gen/typinf.cpp, line 455.

With the commit above, string enums are also accepted.
