[svn r261] Fixed debug info for integer and floating local variables, can now be inspected in GDB. Did a lot of smaller cleans up here and there. Replaced more llvm::Foo with LLFoo for common stuff. Split up tollvm.cpp.

module structs7;

pragma(LLVM_internal, "notypeinfo")
struct S
{
    int i;
    long l;
}

void main()
{
    S s = void;
    int i = s.i;
    long l = s.l;
}
