Removing the ClassHelper caused std::string creation for all calls to
Class::GetDescriptor and a significant performance regression. Make the
std::string an out argument so the caller can maintain it and its life time
while allowing GetDescriptor to return the common const char* case.
Don't generate GC maps when compilation is disabled.
Remove other uses of std::string that are occuring on critical paths.
Use the cheaper SkipClass in CompileMethod in CompilerDriver.
Specialize the utf8 as utf16 comparison code for the common shorter byte
encoding.
Force a bit of inlining, remove some UNLIKELYs (they are prone to pessimizing
code), add some LIKELYs.

Motivation, GCC's compiler warnings are inferior to clang's. -Wthread-safety is
not supported by GCC starting with version 4.7. As this change only effects the
host, performance issues are an impact on host building and testing alone.
Fix clang gtest building on host with BUILD_HOST_64bit.
Fix clang build regressions caused by unused fields.
Fix x86-64 regression caused by requirement to fire-up quick compiler even in an
interpret-only environment. Long-term this code doesn't belong in the quick
compiler.

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.

a given method.
