Added some functions for better fullchip sim

codesign_block - similar to codesign_system, but for quickly doing one
pass of the entire sim on one block
generate_basic_processor_settings - sets up input objects with
reasonable default settings
test_fullchip_block_sim - script setup to test quad core 45nm nehalem
with new setup
Fix to block based test case
