Code cleanup around compiler options and JIT.

Now support passing --verbose-methods and --dump-cfg.

Test: test.py
Test: ./out/host/linux-x86/bin/art -Xcompiler-option --dump-cfg=foo.cfg -Xcompiler-option --verbose-methods=run -Xcompiler-option --compiler-filter=quicken -Xusejit:true -cp benchmarks.dex benchmarks.DeltaBlue.java.DeltaBlue
