A concurrent sweeper thread can access the same markbit cell as the main thread during right trimming a fixed array, resulting in a data race on a markbit cell. Previously we checked whether we were currently marking incrementally, filtering out this case. The current check has the benefit of keeping live_bytes accurate (modulo other bugs) until the sweeper starts.

Escape analysis will eliminate the context, if possible. Materialization must then ensure that the materialized object has the right map, and that the context register is set accordingly.

Removed unused name_ field, made bitfield 16-bits long, and moved it to the start of the struct, resulting in a reduction of 8 bytes on both 32 and 64-bit platforms. Most other changes (which prompted this work) are cosmetic:r - Combined redundant enums - Named enum values kConsistently - Consistently use booleans in bitfield, using enum values only for passing information into NewFunctionLiteral - Removed unneeded arguments from NewFunctionLiteral, reducing clutter at callsites - Added const correctness consistently Review URL: https://codereview.chromium.org/1566053002 Cr-Commit-Position: refs/heads/master@{#33194}

Originally, only BindingIdentifiers were a legal operand for the `...` ellipsis in a function rest parameter. This has since changed, allowing the rest array to be destructured. The grammar is now the following: ``` FunctionRestParameter[Yield]: BindingRestElement[?Yield] BindingRestElement[Yield]: ... BindingIdentifier[?Yield] ...

The sloppy block-scoped function declaration placeholder statements are held in parser_zone_-allocated hashtables. These hashtables are not updated when local_zone_s are removed. Therefore, the NewSloppyBlockFunctionStatement method should allocate SloppyBlockScopeFunctionStatements in the parser_zone_ to avoid a use-after-free. Scope fixup code may end up updating something which is thrown away, but this is a small cost and much simpler than removing dead hashtable entries later.

Requesting reservation of a wasm section for experimentation with storing source code meta information, such as source code comments, and also extra inform on presentation of the AST such an `if-block` pattern being presented as a `when` operation. The wasm design already defines unrecognized sections to be ignored, and this reserved section is ignored. This section is only intended to hold source code meta information and to have no effect on code execution. With wasm going live (behind a flag) on v8, I would also like to be able to give people something to play with in terms of the deployed binary code being a useful source code. It's all experimental, but I understand the entire binary format that V8 is currently using is basically a throwaway, and that the working strategy is to get something running and then revisit format decisions. I would like a fixed reserved section number to avoid potential clashes with other projects - although I am not aware of any other calls for addition sections beyond the need for debug info. If a fixed number is not acceptable, then could this patch alternatively ignore all unrecognized sections and perhaps add the section size to them all - something which is already noted todo in the design document?
