b7ff2bd5cd [proxies] Better print for proxies in d8
Function proxies would not be printed so far since they ended up in Function.prototype.toString which only works with Function as a receiver but no Proxy. Additionally added support for more gracefully dealing with recursive __proto__ structures introduced by proxies.

drive-by-fix: use IS_PROXY if possible in .js files.

e10fdbed6d [proxies] Limit recursive proxy prototype lookups to 100'000
Creating proto-recursive proxies might lead to instanceof while-looping
endlessly in Object::HasInPrototypeChain (For traps we already have stack
guards in place to prevent stack overflows). We prevent this by limiting
the number of proxies we visit in PrototypeIterator to a magic large number.

a878dcfdbc [runtime] Migrate GlobalEval to C++.
The GlobalEval JavaScript function was just a small driver for stuff
implemented in C++ anyway, so there's no point in having it around at
all. The next step will be to move the Function constructor to C++ as
well, which is the other user of %CompileString.

e7373f4285 [Interpreter] Allocates new temporary register outside the reservation for consecutive registers.
Consecutive registers are allocated in two passes. First we "reserve"
a set of registers and these get allocated when we actually use them.
If we request for a temporary register before we use all the consecutive
registers, the earlier implementation does not gaurantee that it allocates
outside the reservation for consecutive registers. This could cause problems
for example, in call_func(a, b++, c). This cl fixes
TemporaryRegisterScope::NewRegister, to return a new temporary register
outside the reservation for consecutive registers.

424ef009a5 Reland of Add web compat workarounds for ES2015 RegExp semantics (patchset #3 id:40001 of https://codereview.chromium.org/1543723002/ )
Unexpectedly, websites depend on doing feature testing with
RegExp.prototype.sticky and browser testing with RegExp.prototype.toString().
ES2015 newly throws exceptions for both of these. In order to enable shipping
new ES2015 semantics, this patch puts in narrow workarounds for those two
cases, keeping their old behavior. UseCounters are added for how often
those particular cases come up, so we can see if it can be deprecated.

This reland replaces problematic legacy const usage with var, to
avoid issues with nosnap builds.

d33b8f20d5 [turbofan] Remove some dead code in move optimizer.
There was no use for the second temp vector, and the one we
are using is scoped to certain methods, and that scope can be
further restricted.

I'm curious if there is really any value in having the temp
vector instead of allocating a function-scoped local. Will
verify that separately.

4acca53e62 [runtime] Rewrite Function.prototype.toString in C++.
There's actually no point trying to do Function.prototype.toString in
JavaScript, as it always calls into C++ at least once, so it only
complicates things (esp. once we start optimizing bound functions).

Drive-by-fix: Rename FunctionApply and FunctionCall builtins to also
reflect the fact that these are builtins in the Function.prototype and
not on Function itself.

dd31b080f2 X87: Change the test case for X87 RunFloat64Add and RunFloat64Sub
The CL #32908 (https://codereview.chromium.org/1526293002) updated the Float64 test data and cause the RunFloat64Add and RunFloat64Sub test cases failed.

  The reason is same as the CL #31808 (issue 1430943002,  X87: Change the test case for X87 float operations), please refer: https://codereview.chromium.org/1430943002/

  Here is the key comments from CL #31808
  Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function,
  those inlined functions has different behavior comparing with GCC ia32 build and x87 build.
  The major difference is sse float register still has single precision rounding semantic. While X87 register has no such rounding precsion semantic when directly use register value.
  The V8 turbofan JITTed has exactly same result in both X87 and IA32 port.

  So we add the following sentence to do type case to keep the same precision for RunFloat64Add and RunFloat64Sub.
  Such as: volatile double  expect = *i +/- *j; // *i +/- *j, etc.

dcac1f144e [wasm] Fixed float-to-int32 conversion to match the spec.
The new implementation detects if the input value is outside i32 range
and traps it that case.

The range check is done as follows:
The input value is converted to int32 and then back to float. If the
result is the same as the truncated input value, then the input value
is within int32 range.

  smaller code with no branches.)
- Use conditional compare to merge branches where appropriate.
- Make use of Ldrsw + UntagSmiFieldMemOperand to load smis more
  efficiently.
- Only load 'undefined' and 'null' once per builtin.
- A few other small improvements.

36afb789e6 PPC: [es6] Correct Function.prototype.apply, Reflect.construct and Reflect.apply.
Port 5bd4832492

Original commit message:
    Introduce a new Apply builtin that forms a correct and optimizable
    foundation for the Function.prototype.apply, Reflect.construct and
    Reflect.apply builtins (which properly does the PrepareForTailCall
    as required by the ES2015 spec).

    The new Apply builtin avoids going to the runtime if it is safe to
    just access the backing store elements of the argArray, i.e. if you
    pass a JSArray with no holes, or an unmapped, unmodified sloppy or
    strict arguments object.

5c33ac6ccd PPC: [runtime] Drop FIRST/LAST_NONCALLABLE_SPEC_OBJECT instance type range.
Port aafc3e5484

Original commit message:
    The FIRST-LAST_NONCALLABLE_SPEC_OBJECT_TYPE range was accidentially used
    in field type tracking, where we should check for JSReceiver instead
    (there's no need to exclude JSProxy or JSFunction from tracking).

    And the use in %_ClassOf was actually wrong and didn't match the C++
    implementation in JSReceiver::class_name() anymore. Now it's consistent
    again.

Port 0794c3c9b9

Original commit message:
    As required by the spec, the second return value now returns success
    also for the range between 0 and -1 where the conversion results in 0.

b10d24ff2c [Interpreter] Add basic deoptimization support from TurboFan to Ignition.
Adds support for generating deoptimization translations for interpreter
stack frames, and building interpreter frames for these translations
when a function deopts. Also adds builtins for
InterpreterNotifyDeoptimized which resume the function's continuation at
the correct point in the interpreter after deopt.

a4e3a3b6a8 [heap] Move to LAB-based allocation for newspace evacuation.
This CL prepare newspace evacuation for parallel execution wrt. to actual
allocations. The priority for allocations is:
* Try to allocate from LAB if objects are below kMaxLabObjectSize
* Allocate directly (synchronized) from newspace for larger objects.
* Fall back to old space allocation (which will be backed by a local compaction
  space in future).

Semantical change: Previously we did fall back to regular new space promotion if
we are OOM in old space. With this CL we fall back to new space promotion, which
could fail because of fragmentation, again leading to an old space allocation
that finally bails into OOM.

Newspace evacuation is still single threaded and requires further changes to
allocation site tracking.

32211800d8 [Interpreter] Generate valid FrameStates in the Bytecode Graph Builder.
Adds FrameState nodes to graphs built by the Bytecode Graph Builder, in
preparation for adding deopt support. Also adds a new
FrameStateType::kInterpretedFunction to allow for specialized deopt
stack translation for interpreted frames. Finally adds support for
disabling typed lowering of binary ops, since the current approach
relies on a FrameState hack which does not apply to interpreted frames
