742873c652 [turbofan] Fix a stack overflow on too many nested bound functions
The stack overflow used to occur when too many bound functions
are nested. The CL also adds a regression test.

90a2430388 Optimize JSCallWithArrayLike with diamond speculation when probable arguments list is empty literal array
The JSCallWithArraylike can be replaced with a JSCall if its probable arguments list is empty literal array. This replacement will introduce a deoptimization check to make sure the length of arguments list is 0 at runtime.

This CL change this optimization to a diamond speculation which may help avoid deoptimization once and keep the fast path. This change may benefit a following usecase,

function calcMax(testArray) {
     Array.max = function(array) {
         return Math.max.apply(Math, array);
     };

     var result = [];
     for (var i = 0; i < testArray.length - 3; i++) {
         var positiveNumbers = [];
         for (var j = 0; j < 3; j++) {
             if (testArray[i + j] > 0) {
                 positiveNumbers.push(testArray[i + j]);
             }
         }
         result.push(Array.max(positiveNumbers));
     }
     return result;
 }

 testArray = [-1, 2, 3, -4, -5, -6, -7, -8, -9, 10];

 for (var i = 0; i < 1000000; i++) {
     calcMax(testArray);
 }

dfa9fbc599 [compiler] Bug in GetOwnFastDataPropertyFromHeap representation handling
The bugfix yesterday missed a case (CL
758816f438).

A better approach is to compute the ideal representation of the
value, then check if it can be in-place changed to the
recorded representation.

cb6218cab0 [liftoff] Fix merges with moves of cache registers
We did not handle conflicts between regular register moves and the
cached instance / cached memory start correctly. This could lead to us
overwriting a regular register when restoring the cached instance, which
results in either crashes or miscalculations afterwards.

758816f438 [compiler] Representation mismatch detection missed a case
In GetOwnFastDataPropertyFromHeap, we read a property value
then compare it with the expected representation. We already
had code to bail out of that particular optimization if there
was a mismatch, however it missed the case of expected
representation being a HeapObject, and when a Smi value was found.

The fix is to use the excellent pre-existing method
Object::FitsRepresentation() to make this check. Thusly, all
cases are handled.

6a1063c899 [compiler] TSAN data race on HeapNumber::value_as_bits()
TurboFan reads the value in HeapNumber, and TSAN detects a data
race between this read and sets on the main thread elsewhere.
We mark this as relaxed atomic (meaning, correct value of the read
is not guaranteed). The compiler uses the dependency mechanism
to re-read the value safely on the main thread later, and aborts
compilation if a change is detected.

a41f5bee79 [wasm] Only print compiler for proper functions
The new DCHECK fires when the tier was set to {kNone}, which was the
case for wrappers.
Since the compiler is only interesting for proper Wasm functions, we
keep the DCHECK but only print the compiler for code objects that
represent actual Wasm functions.

a4b573e5cc [bigint] Fix Karatsuba intermediate result length
When adding up the results of the recursive steps, the Karatsuba
algorithm can temporarily have intermediate results that are one
bit bigger than the final result. This patch makes sure we handle
that case correctly.
Since that extra bit would always get subtracted again, the old
code would not have caused incorrect results or memory corruption,
but it did run into DCHECK-failures, and potentially could have
caused segfaults.

To enable inlining, we make sure to only emit the tierup check
for the main (non-inlined) function and skip it for any inlined
functions.

https://github.com/tc39/ecma262/pull/1490 changed the spec so that the
"name" property of a class should be installed after "length" but before
"prototype". This CL adapts accordingly.

After this change, there is now no need for the separate code path to
set the "name" accessor at runtime. Delete the relevant runtime code as
well.

... which didn't properly handle non-Smi integer indices with
JSTypedArray receivers.

The addition of new JSReceiver::OrdinaryDefineOwnProperty() overload
with LookupIterator::Key caused circular dependency between lookup.h
and js-objects.h, so the LookupIterator::Key was moved out of the
LookupIterator class in order to make it forward-declarable.

9711289d06 A jump-table implementation for constant case switch statements
The change is made since for switch statements with lots of cases,
where each case is a constant integer, the emitted bytecode is still
a series of jumps, when we can instead use a jump table.

If there are 6 or more cases (similar to GCC) of Smi literals, and
if the max Smi case minus the min Smi case is not more than 3 times
the number of cases, we use a jump table up front to handle Smi's,
and then use traditional if-else logic for the rest of the cases.

We then use the jump table in interpreter/bytecode-jump-table to
do the optimization.

This tries to go off issue 9738 in v8's issue tracker. It is not
exactly the same, since that recommends doing the work at JIT-time,
but has similar ideas. It also partially goes off issue 10764.

6288483b65 [compiler] Fix an issue with deprecated maps
Various field dependencies assume that the receiver map and the field
owner map agree on field meta data. That's not necessarily true when
the receiver map is already deprecated. We should skip over deprecated
maps.

- Fix a bug in SerializerForBackgroundCompilation. It used to process
  even deprecated maps.
- Fix a bug in FilterRelevantReceiverMaps. It used to store the original
  map rather than the new version.
- Turn some compilation dependency DCHECKs into CHECKs.
- CHECK in MapRef::FindFieldOwner that the map is not deprecated. While
  there might be valid use cases for calling the underlying
  Map::FindFieldOwner on a deprecated map, we never want to do that in
  the compiler.

Note that we skip any deprecated maps in JSNativeContextSpecialization's
ReduceNamedAccess. That's why I believe the issue could only be observed
with --concurrent-inlining and only in the form of a failing DCHECK.
