1725	* Give the compiler a hint that an expression is very likely to hold true.
1726	*
1727	* Some compilers support explicit branch prediction so that the CPU backend
1728	* can hint the processor and also so that code blocks can be reordered such
1729	* that the predicted path sees a more linear flow, thus improving cache
1730	* behaviour, etc.
1731	*
1732	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1733	* this compiler feature when present.
1734	*
1735	* A few notes about the usage:
1736	*
1737	* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1738	*
1739	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1740	* have some _strong_ reason to do otherwise, in which case document it),
1741	* and/or RT_LIKELY() with success condition checks, assuming you want
1742	* to optimize for the success path.
1743	*
1744	* - Other than that, if you don't know the likelihood of a test succeeding
1745	* from empirical or other 'hard' evidence, don't make predictions unless
1746	* you happen to be a Dirk Gently character.
1747	*
1748	* - These macros are meant to be used in places that get executed a lot. It
1749	* is wasteful to make predictions in code that is executed rarely (e.g.
1750	* at subsystem initialization time) as the basic block reordering that this
1751	* affects can often generate larger code.
1752	*
1753	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1754	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1755	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1756	*
1757	*
1758	* @returns the boolean result of the expression.
