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 nested5;
extern(C) int printf(char*, ...);

void main()
{
    int i = 42;

    printf("Hello world %d\n", i++);

    class C
    {
        void func()
        {
            printf("Hello nested world %d\n", i++);
            //i++;
        }
    }

    auto c = new C;
    c.func();
    printf("i = %d\n", i);
    assert(i == 44);
