[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 bug15;

bool bool1(bool b) {
    if (b) return true;
    else return false;
}

bool bool2(bool b) {
    if (b) {return true;}
    else {return false;}
}

void main()
{
    assert(bool1(true));
    assert(!bool2(false));
}
