/* LIns classes, as required for --random mode. Includers must define a CL___
* macro of the following form:
*
* #define CL___(name, only64bit, relFreq) ...
*
* Selected arguments can be used within the macro expansions.
*
* Field Description
* ----- -----------
* name Name of the instruction class. The types are B (boolean), I
* (32-bit integer), Q (64-bit integer), F (64-bit float), N
* (null). A name of the form LOP_Z_XY means that it takes
* arguments of type X and Y and produces a result of type Z.
*
* relFreq We weight each class differently, so that some classes are more
* common than others. This field gives the relative frequency of
* the instruction class. All the relFreqs together can sum up to
* any number, but it's easier to think about if the sum is a
* round number. (That's why the relFreqs add up to 100%; the
* running total is shown in comments.) The sum also shouldn't be
* too big, as we generate a table with that many elements in it.
*
* Note that we want a decent number of value sinks (eg.
* stores, calls, guards) and not too many value sources (eg.
* immediates, loads) so that the amount of dead code generated is
* reasonable.
*
* Because certain opcode classes aren't supported on all platforms, CLxyz must be one
* of the following:
*
* CL___: for opcode classes supported on all platforms.
* CL_64: for opcode classes supported only on 64-bit platforms.
