O3 CPU: Improve handling of delayed commit flag
The delayed commit flag is used in conjunction with interrupt pending flag to
figure out whether or not fetch stage should get more instructions. This patch
clears this flag when instructions are squashed. Also, in case an interrupt is
pending, currently it is not possible to access the instruction cache. This
patch allows accessing the cache in case this flag is set.
