[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 bug39;

struct S
{
    long l;
}

void main()
{
    S s;
    s.l = 23;
    void* p = &s;
}
