da3b266150 [heap] Move to two-level free-list
Before this CL, free memory (FreeSpace) has been managed through a global free
list that contains single-linked lists of FreeSpace nodes for each size class.

We move away from this approach to a global two-level doubly-linked list that
refers to singly-linked lists of FreeSpace nodes on the corresponding pages.
This way we can refill on a page-level granularity. Furthermore, it also enables
constant-time eviction of pages from the free list.

6c8fc936d2 Move FastAccessorAssembler from RawMachineAssembler to CodeStubAssembler.
(The goal is to have CodeStubAssembler be the sole assembler-like user of
the TF compiler pipeline; with RMA being a private implementation detail
and FAA being a client.)

f507bc1c72 [serializer] Add API to warm up startup snapshot with an additional script.
A startup snapshot is considered cold when it does not contain any
function code. We can now create a warm startup snapshot from a cold one
by running a warm-up script. Functions exercised by the warm-up script
are compiled and its code included in the warm startup snapshot. Side
effects caused by the warm-up script does not persist.

831add808d X87: [wasm] Int64Lowering of Int64Sub on ia32 and arm.
port 33c08596e1 (r34808)

  original commit message:
  Int64Sub is lowered to a new turbofan operator, Int32SubPair. The new
  operator takes 4 inputs an generates 2 outputs. The inputs are the low
  word of the left input, high word of the left input, the low word of the
  right input, and high word of the right input. The ouputs are the low
  and high word of the result of the subtraction.

  The implementation is very similar to the implementation of Int64Add.

  @v8-arm-ports: please take a careful look at the implementation of sbc
  in the simulator

479a2df31a [crankshaft] Specialize JS runtime calls to the native context.
Since Crankshaft specializes to the native context anyways, we don't
need the indirection of loading from the native context and calling the
JS runtime function indirectly, but we can just specialize to the JS
runtime function from the native context and emit a direct (constant)
function call.

f9db79ebdb Ship ES2015 restrictions on function declaration locations
Function declarations were previously permitted by V8 in many locations
which no ECMAScript specification allowed; the ECMAScript 2015 spec
enumerates a few locations (in blocks, as well as after labels and in
conditionals when in sloppy mode). This patch ships the flag to restrict
the usage of function declarations to those contexts.

eee34dd50f Introduce "optimized_out" oddball marker for compilers.
This introduces {optimized_out} as another Oddball kind to be used by
optimizing compilers when values are being optimized away. The aim is
providing visibility when this value leaks into the application domain.
Currently this will lead to {undefined} values appearing which then
silently propagate through the application. The special oddball can be
identified easily as a bug and also the debugger can treat it specially
when needed.

5d62db7430 Revert "Detect cache line size on Linux for PPC hosts."
along with "[arm64] Fix i/d cache line size confusion typo"

which were building on it.

This reverts the following commits:
8d7399f9f8
474e6a3d6d
c3ff68b6b7

Reason for revert: We're getting a large number of crash reports from
arm64 devices that are obviously related to cache flushing after code
patching. Bisection results say that the problems started at revision
c3ff68b. Since I can't find a bug in that CL except for the typo that
I've fixed in 474e6a3 (which made some of the crashes go away but not
all of them), we have no choice but to revert the changes in order to
get stability under control while we investigate.

43f65e89f2 X87: Change the test case for X87 Run_WasmF32SConvertI64/Run_WasmF64SConvertI64.
The CL  (https://codereview.chromium.org/1779123002/) added the Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 test cases and X87 failed at them.

  The reason is same as the CL  (Issue 1649323002: X87: Change the test case for X87 RunRoundInt32ToFloat32), please refer: https://codereview.chromium.org/1649323002.

  Here is the key comments from CL :
  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.

  For CHECK_EQ(a, b) function, if a and b are double or float, it will has similar behaviors like CheckFloatEq(...) and CheckDoubleEq(...) function when compiled by GCC and causes the test case fail.

  So we add the following sentence to do type case to keep the same precision for Run_WasmF32SConvertI64/Run_WasmF64SConvertI64. Such as: volatile double expect = static_cast<float>(*i).

  ahaas put those codes in CHECK_FLOAT_EQ and CHECK_DOUBLE_EQ macros in CL  (https://codereview.chromium.org/1773513002 ).

  So this CL replaced the CHECK_EQ in Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 to CHECK_FLOAT_EQ/CHECK_DOUBLE_EQ for x87 can pass Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 tests.

b82e10d39d [crankshaft] Generate lazy bailout point for HProlog instruction only when it is necessary.
This fix removes unnecessary nops from function prolog and seems to recover performance regression on some of SunSpider benchmarks.

33c08596e1 [wasm] Int64Lowering of Int64Sub on ia32 and arm.
Int64Sub is lowered to a new turbofan operator, Int32SubPair. The new
operator takes 4 inputs an generates 2 outputs. The inputs are the low
word of the left input, high word of the left input, the low word of the
right input, and high word of the right input. The ouputs are the low
and high word of the result of the subtraction.

The implementation is very similar to the implementation of Int64Add.

@v8-arm-ports: please take a careful look at the implementation of sbc
in the simulator.

a regular elements load stub on string wrapper elements. The polymorphic

8a809501bd [compiler] Introduce code stubs for abstract equality.
Add EqualStub and NotEqualStub, based on the CodeStubAssembler, and hook
them up with TurboFan and Ignition. The stubs are a full implementation
of abstract equality for ES6 plus the current SIMD.js draft, unlike the
generic version of the CompareIC, which only implements a subset with
funky runtime fallbacks.

Drive-by-fix: Introduce some common helper methods.

7f363d5d47 [test] Remove feature to mark flaky tests.
The feature was removed from the bots a while ago. It was
superseeded by the flaky-test detection which reruns tests.

Remaining tests still marked as flaky most certainly pass
since a while.

Referencing all the bugs whose expectations lines get
removed by this.
