The test fails because of the race condition between concurrent GC
threads and the destructor of the test.

Make runtime-call-stats a compile-time flag. Disabling RCS saves roughly
1MB binary size on 64bit systems and yields minor performance
improvements.

Scopes in V8 are used to guarantee one or more properties during its
lifetimes. If a scope is not named e.g MyClassScope(args) instead of
MyClassScope scope(args) it will get created and automatically destroyed
and therefore, being useless as a scope. This CL would produce a
compiling warning when that happens to ward off this developer error.
Follow-up to ccrev.com/2552415 in which it was introduced and
implemented for Guard classes.

API calls made via the CallApiCallback builtin, which is used from the
ICs and optimized code, are currently misattributed to the wrong counter
InvokeFunctionCallback instead of FunctionCallback. In addition we don't
use the C trampoline when only runtime call stats are enabled, but the
Chrome DevTools profiler is not active, which means that these calls
will not be attrituted properly at all, and that had to be worked around
using all kinds of tricks (i.e. disabling fast-paths in ICs when RCS is
active and not inlining calls/property accesses into optimized code
depending on the state of RCS).
All of this was really brittle and only due to the fact that the central
builtin didn't properly check for RCS (in addition to checking for the
CDT profiler). With this fix it's now handled in a central place and
attributed to the correct category, so user code doesn't need to worry
about RCS anymore and can just call straight into the fast-path.
Drive-by-fix: Do the same for AccessorInfo getter calls, which share the
core hand-written native code with the API callback logic.
