[PATCH] add rlwinm pattern for DImode for constant building

Hi, 'rlwinm' pattern is already well used for SImode. As this instruction can touch the whole 64bit register, so some constants in 64bit(DImode) can be built via 'lis/li+rlwinm'. To achieve this, a new pattern for 'rlwinm' is added, and 'rs6000_emit_set_long_const' is updated to check if a const
