[svn r229] Updated the object.d implementation to the latest Tango. Fixed a bunch of the built-in typeinfos for arrays, they did not inherit TypeInfo_Array. Applied patch to tango/text/convert/Layout.d by fvbommel, closes #47 . Cleaned up some type code. Replaced uses of llvm::Type with LLType (a typedef), same for Value and Constant. Fixed a few cases where typeinfo for user structs could be emitted multiple times, seems to still be some cases of this :/

module bug3;

struct S
{
    int[] arr;
    char[5] ch;
}

class C
{
    int[] arr;
    char[4] crs;
}

void main()
{
    S s;
    s.arr = new int[5];
    s.arr[1] = 32;
    int i;
    i = s.arr[0];
    //assert(s.arr[0] == 0);
    //assert(s.arr[1] == 32);
}
