52	* Macro for checking if an I/O or MMIO emulation call succeeded.
53	*
54	* This macro shall only be used with the IOM APIs where it's mentioned
55	* in the return value description. And there it must be used to correctly
56	* determine if the call succeeded and things like the RIP needs updating.
57	*
58	*
59	* @returns Success indicator (true/false).
60	*
61	* @param rc The status code. This may be evaluated
62	* more than once!
63	*
64	* @remarks To avoid making assumptions about the layout of the
65	* VINF_EM_FIRST...VINF_EM_LAST range we're checking explicitly for
66	* each exact exception. However, for efficiency we ASSUME that the
67	* VINF_EM_LAST is smaller than most of the relevant status codes. We
68	* also ASSUME that the VINF_EM_RESCHEDULE_REM status code is the
69	* most frequent status code we'll enounter in this range.
70	*
71	* @todo Will have to add VINF_EM_DBG_HYPER_BREAKPOINT if the
72	* I/O port and MMIO breakpoints should trigger before
73	* the I/O is done. Currently, we don't implement these
74	* kind of breakpoints.
