Summary:
Change the way ASan flag parsing is performed at activation: instead
of overwriting all ASan and common flags from the activation string,
ASan will now only override a handful of whitelisted flags.
This is a first step towards making runtime flags immutable after
initialization. I plan to re-factor the activation stragegy to
the following one:
- Parse commandline flags. Override the defaults from compile
definition, env var, etc. Flags are immutable at this point.
- Initiailize the runtime from commandline flags.
- If ASan needs to be started deactivated, stash the runtime
state in "asan_deactivated_flags" and deactivate the runtime.
- When ASan is activated, override "asan_deactivated_flags" with
activation flags, and use it to re-activate the runtime.
