/** @def RT_LIKELY
* Give the compiler a hint that an expression is very likely to hold true.
*
* Some compilers support explicit branch prediction so that the CPU backend
* can hint the processor and also so that code blocks can be reordered such
* that the predicted path sees a more linear flow, thus improving cache
* behaviour, etc.
*
* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
* this compiler feature when present.
*
* A few notes about the usage:
*
* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
*
* - Generally, use RT_UNLIKELY() with error condition checks (unless you
* have some _strong_ reason to do otherwise, in which case document it),
* and/or RT_LIKELY() with success condition checks, assuming you want
* to optimize for the success path.
*
* - Other than that, if you don't know the likelihood of a test succeeding
* from empirical or other 'hard' evidence, don't make predictions unless
* you happen to be a Dirk Gently character.
*
* - These macros are meant to be used in places that get executed a lot. It
* is wasteful to make predictions in code that is executed rarely (e.g.
* at subsystem initialization time) as the basic block reordering that this
* affects can often generate larger code.
*
* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
* and RT_UNLIKELY(). Should you wish for prediction free status checks,
* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
*
*
* @returns the boolean result of the expression.
* @param expr The expression that's very likely to be true.
* @see RT_UNLIKELY

*
* The best is to use this macro right after the class declaration.
