Create CompilerOptions

Package up most compiler related options in CompilerOptions. Details include:
- Includes compiler filter, method thresholds, SEA IR mode.
- Excludes those needed during Runtime::Init such as CompilerCallbacks and VerificationResults.
- Pass CompilerOptions to CompilerDriver.
- Remove CompilerOptions from Runtime.
- Add ability to pass options for app and image dex2oat to runtime via
  -Xcompiler-option and -Ximage-compiler-option respectively.

Other
- Replace 2x CompilerCallbacks implementations with one.
- Factor out execv code for use by both image and oat generation.
- More OatFile error_msg reporting.
- DCHECK for SuspendAll found trying to run valgrind.
