def LSL(self, a):
r = a << <NUM_LIT:1><EOL>self.clear_NZVC()<EOL>self.update_NZVC_8(a, a, r)<EOL>return r<EOL>
Shifts all bits of accumulator A or B or memory location M one place to
the left. Bit zero is loaded with a zero. Bit seven of accumulator A or
B or memory location M is shifted into the C (carry) bit.

This is a duplicate assembly-language mnemonic for the single machine
instruction ASL.
