Fix Bug 327284. The condition code of risbg was not correct.
This instruction might be used by by gcc for masking out bits,
e.g. code like
n &= 3;
if (n == 0)
might result in
risbg %r4,%r4,62,128+63,0
je <target>
The old code set the condition code depending on the operand before
masking. Fix it. This patch also indicates that we need test suite
coverage for risbg and friends.
