Added pragma(llvmdc, "string") for misc per-module compiler configuration, currently "string" can only be "verbose" which forces -vv for module it appears in. Reimplemented support for nested functions/class using a new approach. Added error on taking address of intrinsic. Fixed problems with the ->syntaxCopy of TypeFunction delegate exp. Removed DtoDType and replaced all uses with ->toBasetype() instead. Removed unused inplace stuff. Fixed a bunch of issues in the runtime unittests, not complete yet. Added mini tests.

module stdiotest2;
import std.stdio;
void main()
{
    int[4] v = [1,2,3,4];
    {
        writefln("%s", v);
        {
            int[] dv = v;
            {writefln("%s", dv);}
        }
    }

    {
        writefln(v);
        {
            //int[] dv = v;
            //{writefln(dv);}
        }
    }
    //writefln(1,2,3,4.56,"hello",v);
