8a00950303 [arm] Drop SMMLS support. 
Apparently

 SMMLS r, b, c, a

computes

 r = ((a << 32) - b * c) >> 32

while the documentation is kinda misleading and states that it should
compute

 r = a - ((b * c) >> 32)

The actual behavior is kinda useless, so we drop the instruction again.

0f5949d605 Fix scheduler to correctly schedule nested diamonds. 
The scheduler rewires control based on the last *control*
node that appears in the schedule of a block. This is not
sufficient to account for dependencies.

This patch adds additional dependencies to floating control
nodes. Given a floating control node A, every non-control
dependency of every node B that depends on A is introduces
as an additional dependency of A.

This allows the scheduler to correctly schedule two
diamonds A, B, if their only correct schedule is to
schedule B into the ifTrue successor in A.

363ac55a5d Script streaming: UTF-8 handling fix. 
The problem was that there can be several multi-byte UTF-8 characters near the
splitting point of the data chunks, and the code didn't handle it properly.

This was also the source of crbug.com/417891 - I thought the crash can only
happen when V8 is passed invalid UTF-8 data, but it can also happen in the
abovementioned case. After the fix, we handle the valid UTF-8 case and also
guard against invalid UTF-8 data.

0dd69ec439 Allow identifier code points from supplementary multilingual planes. 
ES5.1 section 6 ("Source Text"):
"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."

This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."

This patch is to reflect this spec change.

bb5b39260b Relax representation requirement in FrameStates. 
This change enables non-tagged representations in FrameStates.

That allows us to run zlib with deoptimization support and have almost the same performance of the generated code (as the code with no deoptimization). Unfortunately, the frame states seem to confuse typer. As a consequence, we generate more representation changes, which in turn causes the scheduler to take a lot more time and memory (>4x). The added compiler time makes zlib with deopt be about 50% slower.

db33f07f79 [turbofan] Reenable value numbering. 
Value numbering is now limited to eliminatable operators (i.e. operators
that don't throw and don't write), and uses linear probing instead of
separate chaining.

8617b3acf8 [turbofan] Fix HashCode/Equals for floating point operators. 
Those floating point constant operators require bitwise handling of
their parameters, otherwise 0.0 equals -0.0. This is solved in a
general way by adding new base::bit_equal_to and base::bit_hash
function objects.
