This CL adds a few transformations that clean up the set of reported source ranges. Duplicates, empty, and uncovered ranges are removed, and nested/consecutive ranges are merged if possible.

Due to the dictionary refactoring we ended up calling the superclass' helper which in turn made us decode the values wrongly for the GlobalDictionary. Change-Id: I4298b6a437ef2d84b69b7e980470c3cf5af79944 Reviewed-on: https://chromium-review.googlesource.com/561701Reviewed-by:

Replaces the old PromotionQueue that was kept at the end of to space. This change allows a future implementation to use (a) a thread-local promotion list and (b) enables work stealing for concurrent scenarios.

This is the first step in optimizing Map and Set iterators. This ports all the base functionality including - Set.prototype.entries - Set.prototype.values - %SetPrototypeIterator%.next - Map.prototype.entries - Map.prototype.keys - Map.prototype.values - %MapPrototypeIterator%.next to C++ and removes all the dead code and the previous half JavaScript implementation. The next step is to port core parts to CodeStubAssembler and finally inline the fast-paths into TurboFan directly. The relevant design document is at: https://docs.google.com/document/d/13z1fvRVpe_oEroplXEEX0a3WK94fhXorHjcOMsDmR-8 Most of this work is very similar to how the Array iterator works and we mostly follow the same process for the implementation.

TruncateDoubleToI generated a 32-bit result but did not clear the upper 32 bits. This violated the invariant that the upper 32 bits should be cleared when the result is 32 bits. This change fixes the bug mentioned below. Clearing the upper 32 bits is also done on x64.

Remove all IsHeapObject/IsSmi checks from assembler and also from the macro-assembler functions that Turbofan code generation uses. Note for porters: In case it's unclear which macro-assembler functions need to be modified, it may be best to wait until I split MacroAssembler in a followup-CL, which will make that clear.

Introduce a stripped down version of UseScratchRegisterScope for ARM and use it inside the assembler and macro-assembler. At the exception of the Call instructions, we now use this scope instead of using the ip register directly. This is inspired from how the ARM64 backend works. In general, the benefit of doing this is we can catch cases where ip is being used both by the caller and by the assembler. But more specifically, TurboFan reserves r9 as an extra scratch register because ip can already be used by the assembler. With this utility, we can isolate the cases in the code generator which need an extra register and potentially fix them, allowing us to give r9 back to the register allocator. This patch uncovered places in the assembler where we were using ip unconditionally when we could have re-used the destination register instead.

On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN.

Instead of counting profiler ticks on the shared function info (which is shared between native contexts), count them on the feedback vector (which is not). This allows us to continue pushing optimization decisions off the SFI, onto the feedback vector. Note that a side-effect of this is that ICs don't have to walk the stack to reset profiler ticks, as they can access the feedback vector directly from their feedback nexus.
