When the memory reducer decides whether to do the next GC or not, it
takes into account the number of detached contexts. This may lead to
redundant GCs if the detached contexts are leaking and stay reachable.

With the unified heap all unreachable detached contexts are freed in
one GC, so this heuristic is no longer necessary.

This CL cleans up CompareOperationFeedback by replacing it with a
composable set of flags. The interpreter is changed to collect
more specific feedback for abstract equality, especially if oddballs
are involved.

TurboFan is changed to construct SpeculativeNumberEqual operator
instead of the generic JSEqual in many more cases. This change has
shown a local speedup of a factor of 3-10, because the specific
operator is way faster than calling into the generic builtin, but
it also enables additional optimizations, further improving
runtime performance.

Currently WebAssembly breakpoint information survive disabling and
re-enabling the debugger. This is different from JavaScript, where
they are all removed. The frontend is expected to re-set the
breakpoint then.

Thus this CL remembers all wasm scripts where breakpoints have been set
in the Debug object, and clears them all when the debugger gets
disabled.
