Avoid speculatively computing flags before every potentially trapping
operation and instead do the flags computation when a trap actually
occurs. This gives approximately 30% speedup in emulation.

No need to print pc/npc when we're dumping the whole cpu state.

Make softint op helpers and Leon cache irq manager take a parameter
for CPUState instead of relying on global env. Move the functions
to int{32,64}_helper.c.
