2201d48c56 [Compiler] Don't pass isolate to CompileTopLevelOnBackgroundThread.
Avoid passing isolate to CompileTopLevelOnBackgroundThread and instead
pass AccountingAllocator. This avoids storing isolate on BackgroundParsingTask

aafdfba899 [Compiler] Remove isolate from CompilationInfo.
Removes Isolate from compilation info and instead threads isolate through
function calls. This ensures that we can't access the isolate from
background thread compilations.

f571da954c [compiler] Split compilation timer on caching decision
Rather than having a single script compilation timer, split it into
multiple timers depending on the state of the (blink-owned) code cache
and (v8-owned) complation cache. This is intended to replace both the
script compilation time timer, and the compilation heuristic enum.

Also keep track of why blink might not want us to produce (or consume) a
code cache, and split the compilation timer on this as well.

Note, there is currently no timer for streaming sources, so these won't
show up in the histograms.

dbfe4a49d8 [Modules] Introduce ScriptOrModule and HostDefinedOptions
This patch introduces a new container type ScriptOrModule which
provides the name and the host defined options of the script/module.

This patch also introduces a new PrimitivesArray that can hold
Primitive values, which the embedder can use to store metadata.

The HostDefinedOptions is passed to V8 through the ScriptOrigin, and
passed back to the embedder through HostImportModuleDynamically for
module loading.

Moves creation of the CompilationInfo for unoptimized compilation into the
respective CompilationJobs for Igntition, Fullcode and asm.js. This unifies
the behaviour with respect to the optimized compilation jobs, and enables the
CompileInfo to be owned by the CompilationJob.

As part of this change, we no longer build new dummy ParseInfos for eager inner
functions, instead using just the single outer ParseInfo created during the
actual parsing.

7009015181 [wasm] Throttle the amount of unfinished work to avoid OOM (non-blocking)
It is possible that the foreground task is unable to clear the
scheduled unfinished work, eventually leading to an OOM.

We use either code_range on 64 bit, or the capacity of the code space,
as a heuristic for how much memory to use for compilation.

The change avoids blocking the background threads while we're over
the memory threshold. This is to avoid starving the GC.

1280954d3a [wasm] Throttle the amount of unfinished work to avoid OOM
It is possible that the foreground task is unable to clear the
scheduled unfinished work, eventually leading to an OOM.

We use either code_range on 64 bit, or the capacity of the code space,
as a heuristic for how much memory to use for compilation.

24b7026d73 [compiler] Drive optimizations with feedback vector (reland)
For interpreted functions, use the optimized code slot in the feedback
vector to store an optimization marker (optimize/in optimization queue)
rather than changing the JSFunction's code object. Then, adapt the
self-healing mechanism to also dispatch based on this optimization
marker. Similarly, replace SFI marking with optimization marker checks
in CompileLazy.

This allows JSFunctions to share optimization information (replacing
shared function marking) without leaking this information across native
contexts. Non I+TF functions (asm.js or --no-turbo) use a
CheckOptimizationMarker shim which generalises the old
CompileOptimized/InOptimizationQueue builtins and also checks the same
optimization marker as CompileLazy and InterpreterEntryTrampoline.

This is a reland of https://chromium-review.googlesource.com/c/509716

We still need support for JSFunction self healing due to
liveedit (which for --no-turbo might end up replacing a
forced Ignition function with a FCG function) - we can
remove this once we remove --no-turbo support.

d1d4b9ce51 Implement new Function.prototype.toString --harmony-function-tostring
For functions declared in source code, the .toString() representation
will be an excerpt of the source code.
* For functions declared with the "function" keyword, the excerpt
  starts at the "function" or "async" keyword and ends at the final "}".
  The previous behavior would start the excerpt at the "(" of the
  parameter list, and prepend a canonical `"function " + name` or
  similar, which would discard comments and formatting surrounding the
  function's name. Anonymous functions declared as function expressions
  no longer get the name "anonymous" in their toString representation.
* For methods, the excerpt starts at the "get", "set", "*" (for
  generator methods), or property name, whichever comes first.
  Previously, the toString representation for methods would use a
  canonical prefix before the "(" of the parameter list. Note that any
  "static" keyword is omitted.
* For arrow functions and class declarations, the excerpt is unchanged.

For functions created with the Function, GeneratorFunction, or
AsyncFunction constructors:
* The string separating the parameter text and body text is now
  "\n) {\n", where previously it was "\n/*``*/) {\n" or ") {\n".
* At one point, newline normalization was required by the spec here,
  but that was removed from the spec, and so this CL does not do it.

Included in this CL is a fix for CreateDynamicFunction parsing. ')'
and '`' characters in the parameter string are no longer disallowed,
and Function("a=function(", "}){") is no longer allowed.

a3052cfe22 [compiler] Collect eager inner functions for compilation during renumbering.
This CL modifies the ast-numbering phase to collect function literals which
should be compiled eagerly. This is then used to eagerly compile the inner
functions before compiling the outer function. This will be used to queue
compilation jobs on the CompilerDispatcher in a later CL.

This CL moves the compilation of eager inner functions out of the
GetSharedFunctionInfo function and instead compiles them explicitly. This
simplifies GetSharedFunctionInfo and also means there is no need to pass a
LazyCompilationMode to the function, so this concept has been removed.
