commit fb6f7abcbc92506d302fb18a2c5fc853d2929248
Author: Carl Love <cel@us.ibm.com>

Power PC Fix extraction of the L field for sync instruction
The L field is currently a two bit[22:21] field in ISA 3.0. The size of the
L field has changed over time.
Currently the ISA 3.0 Valgrind sync instruction support code sets the
flag_L for the instruction L field to a five bit value that includes bits
that are marked reserved the sync instruction. This patch fixes the issue for ISA 3.0
to only setting flag_L the specified two bits.
