When delay loading a symbol, Delphi saves rcx, rdx, r8 and r9 to the
stack.  It then calls GetProcAddress(), pops the saved registers and
calls the function.  This works fine if all of the parameters are
ints.  However, since it does not save xmm0 - 3, it relies on
GetProcAddress() preserving these registers if the function takes
floating point parameters.
