9df23510ea Introduce JIT code events dispatcher for the isolate.
The patch introduces a dedicated dispatching class for JIT code events. It is
set as a helper on the isolate.
This allows classes across v8 to break their dependency on Logger and CpuProfiler.
These two became just regular clients of the dispatcher.

49b2320167 [heap] Add page evacuation mode for new->new
Adds an evacuation mode that allows moving pages within new space without
copying objects.

Basic idea:
a) Move page within new space
b) Sweep page to make iterable and process ArrayBuffers
c) Finish sweep till next scavenge

Threshold is currently 70% live bytes, i.e., the same threshold we use
to determine fragmented pages.

60df7abc28 Use float and double for test cases in test-run-wasm-asmjs.cc
The last 4 test cases in test/cctest/wasm/test-run-wasm-asmjs.cc added by the CL 36911 (https://codereview.chromium.org/2061583002) use float_t and double_t type for WasmRunner.
  For examples: At line 249: WasmRunner<float_t> r(&module, MachineType::Uint32());

  But float_t and double_t depends on FLT_EVAL_METHOD macro of compiler. FLT_EVAL_METHOD is variant on different platform, if the FLT_EVAL_METHOD is 2,  both float_t and double_t will be long
  double and gcc or clang will met error when compiling   WasmRunner<long double> r(&module,MachineType::Uint32());

  For more details, please refer:
  float_t: http://www.cplusplus.com/reference/cmath/float_t/
  FLT_EVAL_METHOD: https://en.wikipedia.org/wiki/C99 check the IEEE 754 floating point support section directly.

  This CL used float and double to replace float_t and double_t to avoid this issue.

2f6be682ac Parser: Report use counts once per feature
Reporting use counts by invoking a callback once per occurrence has
a large overhead cost in certain situations, for example when it needs
to be dispatched to a different thread (which is the case for Web Workers).

Parsing large scripts can produce a lot of occurrences (strict/sloppy mode
once per function).

Chromium (the only known user of UseCounters so far) does not actually care
about number of occurrences, but simply whether they happened at least once.
This commit changes behavior to report features at most once, which dramatically
improves performance for impacted use cases, and should not affect the only
known real world usage.

7ceed92ac0 [builtins] Introduce proper Float64Log1p operator.
Import base::ieee754::log1p() from fdlibm and introduce a Float64Log1p
TurboFan operator based on that, similar to what we do for Float64Log.
Rewrite Math.log1p() as TurboFan builtin and use that operator to also
inline Math.log1p() into optimized TurboFan functions.

Also unify the handling of the special IEEE 754 functions somewhat in
the TurboFan backends. At some point we can hopefully express this
completely in the InstructionSelector (once we have an idea what to do
with the ST(0) return issue on IA-32/X87).

Drive-by-fix: Add some more test coverage for the log function.

8c1ba59aee RelocInfo modes were not propagated when computing
MemoryOperands, on IA32. This needed to be fixed so that we can
compile wasm code before creating instances, since the compiled code
needs to be patched up for memory and globals references.

This surfaces in asm-to-wasm scenarios.

Added testing (rather, enhanced existing tests).
Note patch#1 where we fail on ia32, and patch#2 with the fix.

It is expected that temporarily used strings die while they are

them.  If they are used for times, externalization will happen
when they move to an old heap.

In commit b3bfc0bd58, I corrected the source
position of yield-exceptions by not setting the "return position" on returns
that correspond to yields. It turns out that this caused a bug with debug
stepping. The proper fix is to keep the return position on those returns but
additionally attach the yield's source position to the Throw emitted in
VisitYield.

This reverts commit d3a43e47dd.

This patch also adds typed_array_fun and typed_array_protoype to the
native context. These are used in InstallTypedArray to set up the
prototype chain correctly for each typed array sub class. This removes
the need to later monkey patch them prototype chain in typedarray.js.
This mechanism is also used to get hold of the TypedArray in
typedarray.js, removing the need for a global TypedArray.

This patch updates CallRuntime.golden to account for the two extra
native runtime calls. This patch also fixes some formatting issues (by
running git cl format).

This moves processing of jumps out of bytecode array builder and into
bytecode array writer. This simplifies the pipeline by avoiding having
to flush for offset and patch up offsets in bytecode array builder based
on what was emitted by the bytecode array writer.

This also enables future refactorings to add dead code elimination back
into the pipeline, and move processing of scalable operand sizes to the
end of the pipeline (in the bytecode array writer) rather than having to
deal with scalable operand types throughout pipeline.

afb0e7a4bd [turbofan] Fix phi-hinting problem with deferred blocks
Previously, turbofan selected the gap use from first predecessor block when
hinting a phi, unless that block was deferred, in which case the gap move from
the first non-deferred predecessor block was chosen.

This strategy didn't guarantee that an important invariant was maintained: the
predecessor blocks chosen for hinting phis must preceed the phi's block in the
rpo ordering. In most cases the strategy worked, since graphs generated by the
AstGraphBuilder and existing stubs just happened to always generate schedules
where this rpo ordering property for the first predecessor block, but it is
quite possible to generate a code stub by hand that doesn't have this property
(see included test case).

After this CL, the allocator chooses either the the first non-deferred
"rpo-preceeding" block to be the hinting block, or the first deferred
"rpo-preceeding" block if that doesn't exist. In all previously-existing code,
this behavior is the same as the original algorithm, but has the benefit of not
failing in the register allocator in hand-crafted stubs where all the
"rpo-preceeding" predecessors are all in deferred code.

3188210377 Refactor Maps' code_cache
Most maps have a small code cache (often only one entry), so this patch
optimizes memory consumption of such cases by using plain FixedArrays,
only switching to CodeCacheHashTables when the number of cached entries
gets so large that linear-scan lookups get too slow.

On loading inbox.google.com, this gets the aggregate size of all maps'
code caches (there are about 13,600 of them) from 4300 KB to 970 KB.

216bcf9fb3 [turbofan] Initial version of number type feedback.
This introduces optimized number operations based on type feedback.

Summary of changes:

1. Typed lowering produces SpeculativeNumberAdd/Subtract for JSAdd/Subtract if
   there is suitable feedback. The speculative nodes are connected to both the
   effect chain and the control chain and they retain the eager frame state.

2. Simplified lowering now executes in three phases:
  a. Propagation phase computes truncations by traversing the graph from uses to
     definitions until checkpoint is reached. It also records type-check decisions
     for later typing phase, and computes representation.
  b. The typing phase computes more precise types base on the speculative types (and recomputes
     representation for affected nodes).
  c. The lowering phase performs lowering and inserts representation changes and/or checks.

3. Effect-control linearization lowers the checks to machine graphs.

Notes:

- SimplifiedLowering will be refactored to have handling of each operation one place and
  with clearer input/output protocol for each sub-phase. I would prefer to do this once
  we have more operations implemented, and the pattern is clearer.

- The check operations (Checked<A>To<B>) should have some flags that would affect
  the kind of truncations that they can handle. E.g., if we know that a node produces
  a number, we can omit the oddball check in the CheckedTaggedToFloat64 lowering.

- In future, we want the typer to reuse the logic from OperationTyper.

dc78e0d4d7 Immediately promote marked objects during scavenge
It happens that a scavenger runs during incremental marking. Currently scavenger does not care about MarkCompact's mark bits. When an object is alive and marked, and at least one scavenge happens during incremental marking, the object will be copied once to the other semispace in the new_space, and then once to the old_space. For surviving objects this is useless extra work.

In our current attempts (https://codereview.chromium.org/1988623002) to ensure marked objects are scavenged, all marked objects will survive therefore there will be many objects which will be uselessly copied.

This cl modifies our promotion logic so when incremental marking is in progress, and the object is marked, we promote it unconditionally.

46253e743d [esnext] Fix various callsites to use is_resumable, not is_generator
Async functions are built out of generators, but the
SharedFunctionInfo returns false for is_generator. is_resumable is
the broader query. This patch fixes many parts of V8 to refer
to is_resumable as appropriate.

One incidental change is to remove a check for generators extending
classes. This is part of a general check for constructors being the
only thing which can extend classes, so it is removed here and the
error message for the general case is made more accurate.
