target-ppc: Bug Fix: rlwinm
The rlwinm specification includes the ROTL32 operation, which is defined
to be a left rotation of two copies of the least significant 32 bits of
the source GPR.
The current implementation is incorrect on 64-bit implementations in that
it rotates a single copy of the least significant 32 bits, padding with
zeroes in the most significant bits.
Fix the code to properly implement this ROTL32 operation.
Example:
R3 = F7487D82EC6F75DF
rlwinm 3,3,5,12,4
R3 expected : 8DEEBBFD880EBBFD
R3 actual : 00000000880EBBFD (without this fix)
