1348	* Give the compiler a hint that an expression is very likely to hold true.
1349	*
1350	* Some compilers support explicit branch prediction so that the CPU backend
1351	* can hint the processor and also so that code blocks can be reordered such
1352	* that the predicted path sees a more linear flow, thus improving cache
1353	* behaviour, etc.
1354	*
1355	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1356	* this compiler feature when present.
1357	*
1358	* A few notes about the usage:
1359	*
1360	* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1361	*
1362	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1363	* have some _strong_ reason to do otherwise, in which case document it),
1364	* and/or RT_LIKELY() with success condition checks, assuming you want
1365	* to optimize for the success path.
1366	*
1367	* - Other than that, if you don't know the likelihood of a test succeeding
1368	* from empirical or other 'hard' evidence, don't make predictions unless
1369	* you happen to be a Dirk Gently character.
1370	*
1371	* - These macros are meant to be used in places that get executed a lot. It
1372	* is wasteful to make predictions in code that is executed rarely (e.g.
1373	* at subsystem initialization time) as the basic block reordering that this
1374	* affects can often generate larger code.
1375	*
1376	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1377	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1378	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1379	*
1380	*
