4953b17c52 X87: [builtins] Introduce proper Float64Atan and Float64Atan2 operators.
port 89d8c57b9c (r36916)

  original commit message:
  Import base::ieee754::atan() and base::ieee754::atan2() from fdlibm and
  introduce Float64Atan and Float64Atan2 TurboFan operators based on those,
  similar to what we already did for Float64Log and Float64Log1p. Rewrite
  Math.atan() and Math.atan2() as TurboFan builtin and use the operators
  to also inline Math.atan() and Math.atan2() into optimized TurboFan functions.

b2ce1fa20c add use counters for __defineGetter__ failing
We deviate from spec in that, in our implementation, __defineGetter__ on non-
configurable properties returns false instead of throwing a TypeError. This commit
adds a use counter to track how often we would be throwing an error we currently
avoid, to determine if we can change to align with spec or if the spec is not
implementable.

e32d89ce86 Removes unused lines from the test262 status file after roll.
https://crrev.com/d3a95b8a78eefabf884a60bc3d6aac5830b44eb3
The removed tests are a mix of renamed files and tests which have been
removed after the spec was relaxed.

Also marks one test as a test262 failure rather than our failure.

fa5e049055 [compiler] Fix turbofan string allocation
The hash field is supposed to be 4 bytes even in 64-bit. But the
default parameter of StoreObjectFieldNoWriteBarrier using kTagged
will generate 64-bit store. Fix by Replacing kTagged with kWord32.

This causes ~200 test failures on big-endian, because hash field
offset in BE is 12 instead of 8 in LE platforms.

196a0d3a64 X87: [builtins] Introduce proper Float64Log1p operator.
port 7ceed92ac0 (r36914)

  original commit message:
  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).

a933b7044a [Turbofan] Add the concept of aliasing to RegisterConfiguration.
- Adds the concept of FP register aliasing to RegisterConfiguration.
- Changes RegisterAllocator to distinguish between FP representations
when allocating.
- Changes LinearScanAllocator to detect interference when FP register
aliasing is combining, as on ARM.
- Changes ARM code generation to allow all registers s0 - s31 to be
accessed.
- Adds unit tests for RegisterConfiguration, mostly to test aliasing
calculations.

a88d41919a X87: [ia32] Propagate rmodes when computing MemoryOperands.
port 8c1ba59aee (r36911)

  original commit message:
  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.

5cda2db7d3 Fix '[tests] Don't test moves between different reps in test-gap-resolver.cc'
Port fc59eb8a7a

Original commit message:
Moves between operands with different representations shouldn't happen,
so don't test them. This makes it easier to modify canonicalization to
differentiate between floating point types, which is needed to support
floating point register aliasing for ARM and MIPS.

This change also expands tests to include explicit FP moves (both register and stack slot).

4b8128a051 [wasm] Use ChangeSmiToInt32 instead of SmiConstant in wasm.
Signature indices are encoded as SMIs in the function table of a wasm
module. To compare a signature index with the index parameter that is
passed to an indirect function call, we now change the signature index
to an int32 instead of encoding the index parameter as a SmiConstant.
SmiConstants get encoded as NumberConstant nodes in the TF graph, which
can cause the allocation of heap numbers. Heap allocation has to be
avoided for parallel compilation.

cbbcef803b [wasm] Deleting unused parameter from function "consume_u32v"
Merge branch 'master' of https://chromium.googlesource.com/v7/v8 into unused_variables

Removed unused variables "length" from the signature "consume_u32v". The variable length (passed in as a parameter) is not read from the function, rather it set based on the pc_ offset. However, the value set is also not used in the main line of control flow during decoding. This seems to be some dead code.

9f2a18b729 TypedArray.prototype.set uses internal length property, not real one.
TypedArrays store their true length in an internal slot. This is
normally reflected in the .length property, but that property is
configurable. Algorithms which need the length of a typed array are to
use the internal slot, not the property; TypedArray.prototype.set was
not doing this.

4f674da2e9 [ic] Don't compile load interceptor handlers for LoadGlobalIC.
As a result LoadGlobalIC requires different slow stubs for each TypeofMode.

This CL is a prerequisite for not passing variable name to LoadGlobalIC:
the interceptor handler is the only kind of handler that requires a name
and therefore LoadGlobalIC dispatcher does not need a variable name as well.

25d59e9d48 Revert of Reland [heap] Avoid the use of cells to point from code to new-space objects. (patchset #3 id:40001 of https://codereview.chromium.org/2091733002/ )
Reason for revert:
This breaks gc-stress bot: https://chromegw.corp.google.com/i/client.v8/builders/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot

#
# Fatal error in ../../src/heap/mark-compact.cc, line 3715
# Check failed: Page::FromAddress(reinterpret_cast<HeapObject*>(*slot)->address()) ->IsFlagSet(Page::PAGE_NEW_NEW_PROMOTION).
#

I can reproduce locally, and local revert also fixes it -> revert.

Reproduce with:
 out/Debug/d8 --test --random-seed=2140216864 --nohard-abort --nodead-code-elimination --nofold-constants --enable-slow-asserts --debug-code --verify-heap --allow-natives-syntax --harmony-tailcalls test/mjsunit/mjsunit.js  test/mjsunit/es6/tail-call-megatest-shard2.js --gc-interval=500 --stress-compaction --concurrent-recompilation-queue-length=64 --concurrent-recompilation-delay=500 --concurrent-recompilation

(Maybe run in loop; it's flaky when broken; but passes reliably w/ revert.)

e9a93a9c2b Refactor Object.prototype.toString() to use the instance type instead of class_name().
Now we can turn it into a turbofan stub.

Create new instance types JS_ARGUMENTS_TYPE and JS_ERROR_TYPE.

bdc78957e5 Fix Object.prototype.toString() when @@toStringTag is not a string.
ES2017 draft 19.1.3.6: If @@toStringTag is not a string, Object.prototype.toString()
returns [object Object], except in the following cases:
 - Array
 - String
 - Arguments
 - Function
 - Error
 - Boolean
 - Number
 - Date
 - RegExp.

For anything else, e.g., Maps, Sets, TypedArrays, or the global object, toString() returns
[object Object] if @@toStringTag is absent or not a string. In order to be able to
easily identify the global object in d8, we set @@toStringTag to "global"
for d8.

5508e16592 Reland [heap] Avoid the use of cells to point from code to new-space objects.
The reason for reverting was: [Sheriff] Breaks arm debug:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20arm%20-%20sim%20-%20debug/builds/1038.

The problem was the dereferencing of handles for smi checks. It turned out
that these smi checks can be removed anyways, both on arm and on mips.

Additionally some rebasing was necessary.

Original issue's description:

Cells were needed originally because there was no typed remembered set to
record direct pointers from code space to new space. A previous
CL (https://codereview.chromium.org/2003553002/) already introduced
the remembered set, this CL uses it.

This CL
* stores direct pointers in code objects, even if the target is in new space,
* records the slot of the pointer in typed-old-to-new remembered set,
* adds a list which stores weak code-to-new-space references,
* adds a test to test-heap.cc for weak code-to-new-space references,
* removes prints in tail-call-megatest.js
