+flag, etc...
+
+Also splits the masks for popcntb, popcntd, and cmpb. Originally those
+masks would also control other instructions that e5500 does not
+support (so, we either get none or all).
+
+For the lack of means to do tests, those instructions were never
+enabled until now. The new instructions enabled with this patch are:
+popcntb, popcntw, popcntd, bpermd, prtyw, prtyd, cmpb, ldbrx, and
+stdbrx.
