Previously, any AstVisitor subclasses which wanted to make use of the shared stack overflow checking code needed to depend on Isolate. With this patch, it will be easy to create a second InitializeAstVisitor overload taking a stack_limit directly, for use in code that has no Isolate available (such as code running in the parser). AstVisitor subclasses which depended upon the isolate() accessor have been fixed to either have their own isolate_ member or get it from somewhere else convenient.

Perform native context specialization immediately after graph construction (also after inlinee graph construction). This way we can do unified inlining before we go to typing and typed lowering. And we will get better typing due to constants and (checked) type feedback.

This is a first prototype for a rudimentary inlining heuristic allowing enabling of general inlining based existing budget flags. Also note that this approach does not yet work for multi-level inlining, for now the list of candidates is processed exactly once.

- Fairly (round-robin) divide available memory upon compaction tasks. - Ensure an upper limit (of memory) since dividing is O(n) for n free-space nodes. - Refill from free lists managed by sweeper once a compaction space becomes empty. Assumption for dividing memory: Memory in the free lists is sparse upon starting compaction (which means that only few nodes are available), except for memory reducer GCs, which happen in idle time though (so it's less of a problem).

This adds a workaround that zeroes out semaphores before they are initialized. Some versions of sem_init (e.g. GLIBC_2.0) fail to fully zero out the semaphore, leading to {errno == ENOSYS} with subsequent sem_timedwait calls.

This moves JavaScript source files that are bundled with V8 into a separate directory. The goal is to improve code readability and also being able to formalize ideal reviewers by subsequently adding the OWNERS file. These files almost exclusively contain implementations of methods fully specified by ES6. Note that files in the "debug" directory as well as the "d8.js" file aren't affected by this change.

Looking up 'name' and 'message' properties at the same time and loading the properties later can cause assertion failure if one of the properties is an accessor and calling it changes the holder map.

Before this CL, we created one live range per successive set of deferred blocks. For scenarios with many such blocks, this creates an upfront pressure for the register allocator to deal with many ranges. Linear sorts ranges, which is a super-linear operation. The change places all deferred intervals into one range, meaning that, at most, there will be twice as many live ranges as the original set. In pathological cases (benchmarks/Compile/slow_nbody1.js), this change halves the compilation time. We see some improvements elsewhere, notably SQLite at ~4-5%. We may be able to avoid the subsequent merge. Its cost is the additional ranges it may need to create. The sole reason for the merge phase is to provide an unchanged view of the world to the subsequent phases. With the at-most-one splinter model, we may be able to teach the other phases about splintering - should we find perf hindrances due to merging.
