The flag is set when the operation results in MSB changing its state from 1 to 0 or from 0 to 1; otherwise
cleared. However, the flag does not change if (.L) is selected as the size specifier (.size).
The flag is set when the operation results in MSB = 1; otherwise cleared.
The flag is set when the operation results in 0; otherwise cleared. However, the flag value is undefined if (.L)
is selected as the size specifier (.size).
The flag is set when the bit shifted out last is 1; otherwise cleared. However, the flag is indeterminate if (.L)
is selected as the size specifier (.size).
