It is an invariant that objects in the shared heap never point into per-Isolate heaps. This is currently broken by DependentCode. At the same time, shared maps and other holders of DependentCode are designed to never invalidate optimized code. E.g., shared maps are effectively immutable. This CL does two things: 1. Prevent shared objects from being depended upon 2. DCHECK that shared objects never cause deoptimization Bug: v8:12547, v8:12761 Change-Id: I0fedae9134a8f786a9200e70f99dba7b38cd2d80 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3704809Reviewed-by:

LocalHeap only uses LABs for allocation with size below kMaxLabObjectSize. Larger allocations used a path that was unaware of alignment restrictions. Bring implementations of LocalHeap and regular PagedSpace closer together by assuming the caller of their free list allocations takes care of size and alignment adjustments. Drive-by: Use unaligned allocations when possible which avoids a call into PreceedWithFiller(size) which would only bail out late for 0-sized fillers.

In the case of bugs creating shared->local edges, this lets us catch dangling pointers via CHECKs before they happen. Also removed some redundant checks in the shared struct verifier.

SeqStrings have their padding bytes serialized as 0s for deterministic snapshot contents. Currently this is done by mutating the SeqStrings and memsetting their padding bytes to 0 when serializing. This mutation is not threadsafe in the presence of shared strings. This CL removes the mutation by serializing the data and padding payloads separately for SeqStrings.

Reason for revert: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Mac%20-%20arm64%20-%20release/10365/overview Original change's description: > cppgc: Minor fix in cppgc efficiency calculation > > Efficiency calculation (freed bytes over GC duration) assumes that the > duration of the GC is non zero. However, if the clock resolution is > not small enough and the entire GC is very short, the timed value > appears to be zero. This leads to NaN values showing in metrics and > CHECKs failing.

Code for map methods was added a really long time ago but no one ever brought that to set. Adds new common lowering for both collections and updates the SetPrototypeHas builtin. My initial testing shows this to be as much as 50x faster in some cases.
