target-arm: Split data abort syndrome generator
Split the data abort syndrome generator into two versions: One with a valid Instruction Specific Syndrome (ISS) and another without. The following new flags are supported by the syndrome generator with ISS: * isv - Instruction syndrome valid * sas - Syndrome access size * sse - Syndrome sign extend * srt - Syndrome register transfer * sf - Sixty-Four bit register width * ar - Acquire/Release These flags are not yet used, so this patch has no functional change except that we will now correctly set the IL bit in data abort syndromes without ISS information.
