+PEXT returns wrong values, seemingly switches arguments
+
+Hi,
+
+I fiddled with BMI2 instructions and discovered that pext instructions
+emulated with "qemu-x86_64 -cpu Haswell" return the wrong value. It
+seemingly switches up its arguments. I suspect that the error is around the
+gen_helper_pext(...) call in target-i386/translate.c. I checked helper_pext
+in target-i386/int_helper.c and it works fine.
+
+I ran my program on a CPU with BMI2 instruction set too, and it indeed
+returns different values.
+
+I didn't check pdep, it could have the same problem.
