HAS_PROGRESS_BAR is set after page initialization at which point all flags are assumed to be immutable while a GC is running. Separating out the progress bar from flags allows setting it lazily at allocation time.

Jakob Gruber authored
The JSRegExp heap object should not be the source of truth for regexp flags, which are also relevant in places that don't need or want to care about the heap object layout (e.g.: the regexp parser). Introduce RegExpFlags as a new source of truth, and base everything else on these flags. As a first change, remove the js-regexp.h dependency from the regexp parser. Other files in src/regexp/ should be updated in follow-up work.

The heap snapshot view in the dev tools reports a lot of incorrect retaining paths involving weak references from FeedbackVectors. To fix, when IndexedReferencesExtractor encounters a weak reference, it should record a weak reference rather than a hidden reference. This way, the forward reference is still visible when exploring in the summary view, but weak references aren't reported as retainers.

This introduces a new, optional `nonIndexedPropertiesOnly` flag to the `Runtime.getProperties` inspector request, which tells the inspector to only report properties whose name is not an (typed) array index. This is to support retrieving all properties except for the indexed ones when the DevTools front-end decides to use the array bucketing mechanism. Previously the DevTools front-end had some quite complicated logic in place to simulate this via injected JavaScript, but that logic didn't pick up internal properties and was also interfering with the inherited accessor mechanism. With this new flag, it's straight-forward to implement the correct behavior in the DevTools front-end. The corresponding devtools-frontend CL is https://crrev.com/c/3099011.

The optimal implementation is in TurboFan x64 codegen, move it into shared-macro-assembler, and have TurboFan ia32 and Liftoff use it. The optimal implementation accounts for AVX2 support.
