[turbofan] Optimize array destructuring
This CL introduces type narrowing and constant folding reducers
to constant fold code that comes out of inlined destructuring
of arrays. In particular, array iterator introduces code that
contains a phi of a temporary array that blocks escape analysis.
The phi comes from conditional that can be evaluated statically
(i.e., constant folded), so with better constant folding we
allow escape analysis to get rid of the temporary array.
On a quick micro-benchmark below, we see more than 6x improvement.
This is close to the hand-optimized version - if we replace
body of f with 'return b + a', we get 220ms (versus 218ms with
destructuring).
function f(a, b) {
[b, a] = [a, b];
return a + b;
}
function sum(count) {
let s = 0;
for (let i = 0; i < count; i++) {
s += f(1, 2);
}
return s;
}
// Warm up
sum(1e5); sum(1e5);
console.time("destructure array");
sum(1e8);
console.timeEnd("destructure array");
console.timeEnd: destructure array, 213.526000
console.timeEnd: destructure array, 1503.537000

[turbofan] Lower NumberConstant nodes to IntPtrConstant.
If a NumberConstant can be represented as a Smi, then lower it to a
IntPtrConstant node during simplified lowering. Thanks to this, all backends can
match Smi values that can also be encoded as immediates in the instruction
selector. Additionally, we can apply the same lowering to the CodeAssembler for
the snapshot.
As a result, we can remove `mov` instructions generated because Int32Matcher and
Int64Matcher didn't not recognize Smis:
For 32-bit target, it's common for Smis also be immediates: "if (a < 100) {}"
~~~
mov r1, #200 -> cmp r0, #200
cmp r0, r1 -> blt <>
blt <> ->
~~~
On Arm64 particularly, we lose opportunites to use `cbz`: "if (a == 0) {}"
~~~
movz x0, #0x0 -> cbz x1 <>
cmp x1, x0 ->
b.eq <> ->
~~~
Overall, we do not see an impact on benchmarks such as webtooling. However, we
do see noteworthy code size reduction, from 0.5% to 1.5%.
