1311	* Give the compiler a hint that an expression is very likely to hold true.
1312	*
1313	* Some compilers support explicit branch prediction so that the CPU backend
1314	* can hint the processor and also so that code blocks can be reordered such
1315	* that the predicted path sees a more linear flow, thus improving cache
1316	* behaviour, etc.
1317	*
1318	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1319	* this compiler feature when present.
1320	*
1321	* A few notes about the usage:
1322	*
1323	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1324	* have some _strong_ reason to do otherwise, in which case document it),
1325	* and/or RT_LIKELY() with success condition checks, assuming you want
1326	* to optimize for the success path.
1327	*
1328	* - Other than that, if you don't know the likelihood of a test succeeding
1329	* from empirical or other 'hard' evidence, don't make predictions unless
1330	* you happen to be a Dirk Gently.
1331	*
1332	* - These macros are meant to be used in places that get executed a lot. It
1333	* is wasteful to make predictions in code that is executed rarely (e.g.
1334	* at subsystem initialization time) as the basic block reordering that this
1335	* affects can often generate larger code.
1336	*
1337	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1338	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1339	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1340	*
