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 arrays3;

void main()
{
    int[] arr;
    {arr = new int[25];}
    {assert(arr.length == 25);}
    {arr.length = arr.length + 5;}
    {assert(arr.length == 30);}
}
