MC L2 missing FullMatches

[bryates]

The HLS implementation of the MC for L2 has two missing FullMatch entries:

Event: 33
FullMatch 1:
index   reference       computed
0       0x621d0b5210073 0x621d0b5210073
1       0x622522b9fe073 0x622522b9fe073
2       0x640138bc01156 0x640138bc01156
3       0x66012f3a0603d 0x66012f3a0603d
4       0x660523ac011c1 0x0     <=== missing
Event: 41
FullMatch 1:
index   reference       computed
0       0x620906320218b 0x0     <=== missing

which appear if we allow the MC to run for 109 cycles instead of 108. I'm digging more into this to see what's causing the slowdown. This issue exited before PR #207.
