The current implementation overapproximates the
possible_nondeterminism_ bit by setting it whenever a NaN value is
reinterpreted as integer, or stored to memory. This hides bugs in the
interpreter that are handled as possible nondeterminism even though
they are not.
This CL fixes this by only setting the bit if a binary floating point
operation is executed and one of the inputs is a NaN.

Expressions of the form
a_0 + a_1 + a_2 + a_3 + ... + a_n
seem to be reasonably common for cases such as building templates.
However, parsing these expressions results in a n-deep expression tree:
...
/
+
/ \
+ a_2
/ \
a_0 a_1
Traversing this tree during compilation can cause a stack overflow when n is
large.
Instead, for left-associate operations such as add, we now build up an
n-ary node in the parse tree, of the form
n-ary +
/ | \
/ | ... \
a_0 a_1 a_n
The bytecode compiler can now iterate through the child expressions
rather than recursing.
This patch only supports arithmetic operations -- subsequent patches
will enable the same optimization for logical tests and comma
expressions.

Before, the standard way to create a RegList was either:
RegList list = (1 << 0) | (1 << 1) | ...
or
RegList list = rax.bit() | rdx.bit() | ...
The first way allows to make the RegList constexpr, but needs comments
to document which registers you are referring to, and it has no checks
that all bits you set on the RegList actually belong to valid registers.
The second one uses the symbolic names, hence is much more readable and
makes it harder to construct invalid RegLists. It's not constexpr
though, since the {bit()} method on the register types is not constexpr.
This CL adds a constexpr accessor to get the code and bit of a
constexpr Register, and adds a helper method to create a constexpr
RegList like this:
constexpr RegList list = Register::ListOf<rax, rdx, rdi>();
This new method is used in a number of places to test its
applicability. Other uses of the old pattern remain and can be cleaned
up later.

When lowering a monomorphic load/store, where multiple receiver maps
have been recorded, but the action to be performed is the same (i.e.
yielding undefined because the property is not found), TurboFan used
to ignore the Smi case, leading to a pretty terrible deoptimization
loop, as the LOAD_IC/STORE_IC properly recorded that state and thus
didn't change it's state.
Fixing this issue gives a 18-20% boost on the prettier test of the

Previously, V8's slice was implemented in a combination of C++ and a
Javascript fallback. The disadvantage of this approach was that the
fast-path required a call through the CEntryStub, which introduced
considerable overhead for small arrays with fast elements kinds.
Now the implementation primarily uses the CSA to generate both the
full spec-complaint implementation as well as fast paths for argument
objects and arrays with fast elements kinds. The CSA implementation
uses a C++ implementation fallback in select situations where the the
complexity of a CSA implementation would be too great and the
CEntryStub overhead is not decisive (e.g. slices of dictionary
elements arrays).
Performance results on semi-random arrays with small number of
elements (old vs. new):
smi copy: 48.7 ms vs. 12 ms
smi slice: 43.5 ms 14.8 ms
object copy: 35.5 ms 7.7 ms
object slice: 38.7 ms 8.8 ms
dictionary slice: 2398.3 ms vs. 5.4 ms
fast sloppy arguments slice: 9.6 ms vs. 7.2 ms
slow sloppy arguments slice: 28.9 ms vs. 8.5 ms
As a bonus, the new implementation is fully spec-compliant and fixes
at least one existing bug.
