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.

    auto old = tree;
    bark(tree);
    assert(old !is tree);

void main()

    auto w = new wrong;

    foo(w);
    assert(w is old);
