3c3330f6f0 Revert "[interpreter] Separate bytecodes for one-shot property loads and stores"
This reverts commit eccf186749.

Reason for revert: Speculative revert because it seems to introduce a pretty stable flake on gc stress tests, see https://bugs.chromium.org/p/v8/issues/detail?id=8229

93cbb579a6 [Intl] Remove incorrect CHECK
The CHECK was introduced in d7ae63e6f2.

The first time the property got read by ToDateTimeOptions
and the test will cause the needsDefault in ToDateTimeOptions
be false. Then in step 22 of InitializeDateTimeFormat,
it will get all undefined and cause the
skeleton to be empty string. If we only pass in empty options, the
defaults will be filled by ToDateTimeOptions and won't cause any
CHECK failure.

89f52f8a44 [wasm] Load formal_param_count for mismatched import calls
For WASM import calls to JSFunctions where the arity is mismatched,
we currently generate code that inlines the formal parameter count
of the target function as a constant in a call to the arguments
adapter. This CL changes this to generate code that loads the formal
parameter count from the function at runtime in order to permit
more sharing later.

bcb8d49b2c [snapshot] add checksum to startup snapshot
We already had checksumming for code cache data. We now extend
checksumming to the startup snapshot to catch data corruption early.

The performance impact for deserialization is a regression of 1-2%,
which should be acceptable.

Sample output for the included test with --profile-deserialization:

[Verifying snapshot checksum took 0.023 ms]
[Deserializing isolate (134348 bytes) took 1.891 ms]
[Verifying snapshot checksum took 0.024 ms]
[Deserializing isolate (134348 bytes) took 1.654 ms]
[Deserializing context #0 (47208 bytes) took 0.331 ms]
Deserialization will reserve:
    208168 bytes per isolate
    123368 bytes per context #0
Snapshot blob consists of:
    134492 bytes in 6 chunks for startup
    115272 bytes for builtins
     47152 bytes in 31 chunks for context #0
[Verifying snapshot checksum took 0.048 ms]
[Verifying snapshot checksum took 0.043 ms]

eccf186749 [interpreter] Separate bytecodes for one-shot property loads and stores
Create LdaNamedPropertyNoFeedback and StaNamedPropertyNoFeedback
for one-shot property loads and stores. This CL replaces the runtime
calls with new bytecodes for named property load stores in one-shot code.
the runtime calls needed extra set of consecutive registers and
additional move instructions. This increased the size of
bytecode-array and possibly extended the life time of objects.
By replacing them with NoFeedback bytecodes we avoid these issues.

31228a69c3 [Compile] Refactor BackgroundCompileTask to enable its use by CompilerDispatcher
Splits background compilation data out of ScriptStreamingData and into
BackgroundCompileTask. Also makes BackgroundCompileTask no longer a sub-class
of ScriptStreamingTask, and instead have ScriptStreamingTask delegate to a
BackgroundCompileTask.

As part of this change, we now create the CharacterStream on the main thread,
and therefore have to set the (thread-local) runtime_call_stats on the already
created CharacterStream when the BackgroundCompileTask is run on the background
thread. As such, changes to CharacterStream were needed to feed the
runtime_call_stats through appropriately.

Deprecates Source::GetCachedData and StreamedSource::GetCachedData since they are
no longer used, and the streamed source never has cached data (streaming is
suppressed if cached data is available). Also removes Utf8ChunkedStream which

- Fix formatting of operator declarations
- Fix formatting of constexpr if-clauses (the constexpr is now included on the

- Fix formatting of label declarations on callables, the "label" keyword now
  always starts a new line with indentation.
- Remove space after identifier name in generic parameter declarations, e.g.
  "<a : T>" is now "<a: T>" which is consistent with type specification

ce7ec6ef0a [turbofan] Refactor the CheckedInt32Div/CheckedUint32Div lowering.
Improve the lowering of CheckedInt32Div and CheckedUint32Div for the
case that the right hand side is a known (positive) power of two, as
in that case it's sufficient to just check the relevant bits on the
left hand side and then shift by the appropriate amount of bits.

This is significantly faster than what TurboFan is able to generate
from the general lowering, even with all the MachineOperatorReducer
magic (it even shows as a steady ~1.5% overall improvement on the
Kraken crypto ccm benchmark).

Also turn the general CheckedInt32Div lowering into readable code again,
and make sure that all the bailout cases are properly covered by mjsunit
tests (i.e. the "division by zero" bailout was not covered properly).

Without this the call to `formatFailureText` in `test-async.js`

rejections.

Once `formatFailureText` was added it reveals a but where several

test/mjsunit/es6/promise-all.js
test/mjsunit/harmony/async-generators-resume-return.js

test/mjsunit/harmony/async-generators-yield.js

Making equals call `deepEquals` fixed that issue.
