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 mini.assign1;

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

struct X
{
    int a;
    alias a b;
}
void main()
{
    X e = void;
    e.a = e.b = 5;
    printf("%d - %d\n", e.a, e.b);
    assert(e.a == 5);
    assert(e.a == e.b);
}
