We can just use the same trick here that we use with TurboFan and load the (signaling) NaN value out of the canonical tagged root. This improves the loop for initializing double backing stores by hoisting the load of the constant value out of the loop.

When using ninja to build without specifying explicit targets, all existing targets in any BUILD.gn file are built/executed.

For simple replacement strings without $ characters, we can do the replacement in CSA for a global regexp.

Previously, in order to get immortal immovable objects onto the first page, the serializer would iterate the root list twice. The first time it would prioritize immortal immovables. The second time it would serialize the rest. This does not guarantee that immortal immovable objects actually end up on the first page, and by now this is not necessary anymore, since we mark all pages created during heap init as immortal immovable pages.

The existance of an `AllowJavascriptExecutionDebugOnly` scope in `Isolate::ReportPendingMessages()` indicates that the API supports running arbitrary JS code in a `AddMessageListener` callback. Currently, this can fail in debug mode: The `!isolate->external_caught_exception()` condition is checked when entering API methods inside such a handler. However, if there is a verbose `TryCatch` active when the exception occurs, this check fails, and when calling `ToString()` on the exception object leaves a pending exception itself, the flag is re-set to `true`. Fix this problem by clearing the flag and the pending exception if there was one during `ToString()`. This matches the code a few lines up in `messages.cc`, so the exception state is now consistent during the callback. This currently makes a Node.js test fail in debug mode (`parallel/test-error-reporting`).

This CL creates the invariant that the BigInt class treats BigInt objects as immutable. Writing to new BigInt objects as part of their construction is done by the MutableBigInt helper class, which in turn is hidden as an implementation detail in bigint.cc. As a side effect, this refactoring enforces right-trimming checks for all newly created BigInts, and ensures that all BigInt allocations possibly exceeding kMaxLength check for this case and throw a RangeError instead of crashing.

The layout descriptor helper computes the object header size using map->instance_size() and map->GetInObjectProperties(). It races with finalization of slack tracking, which changes both the instance size and the in-object properties count. This patch replaces the in-object properties count byte in the map with the byte that stores the start offset of in-object properties. The new byte can be used in the layout descriptor to compute the object header size and it is immutable. This patch also renames InstanceSize to InstanceSizeInWords where the instance size is represented in words.

The logger for perf does not support relocating code objects so as a result we disable code space compacting to make sure code does not move. However, a a CodeMove event may still happen if a BytecodeArray object moves, which isn't relevant to the perf jit support so we can ignore it.

Add another entry to the NoCacheReason enum, reporting that the chromium ScriptResource has no cache handler. Also, the amount of chromium-specific entries in this enum is getting too high. So, added a TODO for removing them -- possibly in the future we want to do this no-cache reason logging in Chromium after all, propagating isolate cache hits and consume failures back up the API with an out parameter.
