ART: Add support for runtime debug checks
Add support for runtime-switchable debug flags. These flags are only
enabled in debug mode, and a constexpr false in release mode. This
allows to distinguish fast from slow checks, for example.
To simplify usage, two macros should be used. DECLARE_RUNTIME_DEBUG_FLAG
defines a static class member or constexpr as the flag. DEFINE_RUNTIME_DEBUG_FLAG
defines the static storage and registers it, if needed. See the
documentation in logging.h.
As is, runtime checks are disabled by default. Pass -XX:SlowDebug=true
to enable them on startup.
Add logging_test. Fix up tests and scripts to enable slow debug checks.
