Made some updates to the half.ll test under CodeGen to make it friendly to the update_llc_test_checks .py tool as follows:
1.Removing the llc flag -asm-verbose=false
2.Grouping the multiple check-prefix directives
3.Apply update_llc_test_checks.py tool on the test

This change is needed to easily update scheduling changes in an upcoming patch.
