Summary: [AA] Can't set associative array with array as key

This code should compile:
---
void main()
{
int[char[]] aa;
aa[new char[1]] = 5; // line 4
}
---
main.d(4): Error: associative arrays can only be assigned values with immutable
keys, not char[]
---
Also the error message is wrong. The compiler expects an array of not-mutable
elements (yes, `cast(const)` will work). This incorrect compiler hack [1] was
introduced trying to fix Issue 2954 (see Comment 8 of that issue). I propose to
remove the hack.
And yes, it's a regression from 2010. )
