[svn r228] Fixed: when new'ing basic types, the storage was not default initialized. Fixed: the tango/lib/compiler/llvmdc/llvmdc.mak makefile was a bit incorrect. Changed: the basic gc is now the default. Changed: renamed a few temporary names in the LLVM IR output.

    ushort b = 0x0FFF;
    auto t = a & b;
    a &= b;
    assert(t == a);
