The deprecated pipeline is used for asm.js only, where we forcibly
disable inlining anyways (for performance reasons), so inlining via
the AstGraphBuilder is essentially dead code by now, thus there's no
point in trying to keep that around in the code base.

Also nuke the test-run-inlining.cc file, which would require some heavy
surgery (for probably little benefit), and move the useful tests for
mjsunit tests instead.

This fixes a bug where the re-creation of phi nodes leads to divergence. The fix makes sure that once a node created a phi node, it sticks to it and does not forget about it, even if the inputs suddenly agree again. The bug appeared on the trybots in https://codereview.chromium.org/2512733003/.

Also I added a line to mark effect phi nodes on the queue. This is unrelated, but seems to be an obvious ommission.

Add support for WebAssembly.Memory objects to be simultaneously referenced by multiple Instance objects. GrowingMemory should maintain a consistent view of memory across instances.
 - Store a link to instances that share WebAssembly.Memory in the WasmMemoryObject, updated on instantiate.
 - Implement WasmInstanceWrapper as a wrapper around the instance object to keep track of previous/next instances, instance object is stored as a WeakCell that can be garbage collected.
 - MemoryInstanceFinalizer maintains a valid list of instances when an instance is garbage collected.
 - Refactor GrowInstanceMemory to GrowMemoryBuffer that allocates a new buffer, and UncheckedUpdateInstanceMemory that updates memory references for an instance.

For dictionary-mode receivers, the KeyedStoreGeneric stub can store
properties directly in most cases. Doing so avoids the need to have
an entry in the stub cache for every map/property combination.

In order for profiles of optimized code to have accurate source
positions, we need to prepare for this when compiling. If the profiler
is enabled late, this may be missing, leading to inaccurate profile
data. A compromise to solve this is to prepare for accurate positions if
the debugger (and therefore DevTools) is active, even if we are not
currently capturing a profile.

The alternative is to deopt everything upon profiling, but that would
affect the profile significantly.

RuntimeTimerScopes always subtract their own time from the parent timer's
counter to properly account for the own time. Once a scope is destructed it
adds it own timer to the current active counter. However, if the current
counter is changed with CorrectCurrentCounterId we will attribute all the
subtimers to the previous counter, and add the own time to the new counter.
This way it is possible to end up with negative times in certain counters but
the overall would still be correct.
