This adds a new API function and provides a simple implementation of performance.measureMemory() in d8. The implementation currently immediately resolves the result promise with the current heap size.

This speeds up the check by ~10x. This was tested by writing a simple test that compares a for-loop and array.every(): for (var i = 0; i < kMemSize; i++) { assertEquals(0, array[i]); } assertTrue(array.every((e => e == 0))); The for-loop takes ~180s, every() takes ~19s. Numbers above are for arm.debug build (simulator). On x64.debug builds we can see a similar 10x improvement, from ~6s to ~400ms.

This CL changes how variables are resolved during debug evaluate. We now re-parse the whole script when creating a ScopeIterator. This gives us accurate scope information for all parent scopes of the closure in which we stopped. Using this information, we build blacklists of stack-allocated variables. Each context on the chain in between the closure context up to the original native context is wrapped in a debug-evaluate context with such a blacklist attached. Variable lookup for debug-evalute contexts then works as follows: 1) Look up in the materialized stack variables (stayed the same). 2) Check the blacklist to find out whether to abort further lookup. 3) Look up in the original context. Steps 1-3 is repeated for each debug-evaluate context, since they mirror the original context chain.

Reuse the existing builtin and extension infrastructure to provide a garbage collection mechanism that allows for asynchronous execution. On --expose-gc, this changes the gc call to parse parameters the following: (1) Parse options when encountering an options object with known properties. (2) No parameters is parsed as {type: 'major', execution: 'sync'}. (3) Truthy parameter that is not setting options is parsed as {type: 'minor', execution: 'sync'}. (2) and (3) preserve backwards compatibility for existing callers as this may be used widely across various test and benchmarking infrastructures. Valid options: - type: 'major' or 'minor' for full GC and Scavenge, respectively. - execution: 'sync' or 'async' for synchronous and asynchronous execution respectively. Returns a Promise that resolves when GC is done when asynchronous execution is requested, and undefined otherwise. Note: This is implemented as builtin to avoid having any stack at all. This information is also passed to the embedder to allow skipping stack scanning.
