Under the right conditions we can optimize cmp comparisons to cmn
comparisons, such as:
func foo(a, b int) int {
var c int
if a + b < 0 {
c = 1
}
return c
}
Previously it's compiled as:
ADD R1, R0, R1
CMP $0, R1
CSET LT, R0
With this CL it's compiled as:
CMN R1, R0
CSET MI, R0
Here we need to pay attention to the overflow situation of a+b, the MI
flag means N==1, which doesn't honor the overflow flag V, its value
depends only on the sign of the result. So it has the same semantic of
the Go code, so it's correct.
Similarly, this CL also optimizes the case of >= comparison
using the PL conditional flag.

The -test.v=test2json flag causes the testing package to inject extra
control characters in the output to allow the JSON parser to more
gracefully handle extraneous writes to os.Stdout and/or os.Stderr in
the package under test (see CL 443596). However, it doesn't filter out
those control characters because almost no real-world tests will
output them.
It turns out that testing.TestFlag is one of the rare tests that does
output those control characters, because it tests the
-test.v=test2json flag itself.

Currently the pacer is designed to pace against the edge. Specifically,
it tries to find the sweet spot at which there are zero assists, but
simultaneously finishes each GC perfectly on time.
This pretty much works, despite the noisiness of the measurement of the
cons/mark ratio, which is central to the pacer's function. (And this
noise is basically a given; the cons/mark ratio is used as a prediction
under a steady-state assumption.) Typically, this means that the GC
might assist a little bit more because it started the GC late, or it
might execute more GC cycles because it started early. In many cases the
magnitude of this variation is small.
However, we can't possibly control for all sources of noise, especially
since some noise can come from the underlying system. Furthermore, there
are inputs to the measurement that have effectively no restrictions on
how they vary, and the pacer needs to assume that they're essentially
static when they might not be in some applications (i.e. goroutine
stacks).
The result of high noise is that the variation in when a GC starts is
much higher, leading to a significant amount of assists in some GC
cycles. While the GC cycle frequency basically averages out in the
steady-state in the face of this variation, starting a GC late has the
significant drawback of reducing application latencies.
This CL thus biases the pacer toward avoiding assists by picking a
cons/mark smoothing function that takes the maximum measured cons/mark
over 5 cycles total. I picked 5 cycles because empirically this was the
best trade-off between window size and smoothness for a uniformly
distributed jitter in the cons/mark signal. The cost here is that if
there's a significant phase change in the application that makes it less
active with the GC, then we'll be using a stale cons/mark measurement
for 5 cycles. I suspect this is fine precisely because this only happens
when the application becomes less active, i.e. when latency matters
less.
Another good reason for this particular bias is that even though the GC
might start earlier and end earlier on average, resulting in more
frequent GC cycles and potentially worse throughput, it also means that
it uses less memory used on average. As a result, there's a reasonable
workaround in just turning GOGC up slightly to reduce GC cycle
frequency and bringing memory (and hopefully throughput) levels back to
the same baseline. Meanwhile, there should still be fewer assists than
before which is just a clear improvement to latency.
Lastly, this CL updates the GC pacer tests to capture this bias against
assists and toward GC cycles starting earlier in the face of noise.
Sweet benchmarks didn't show any meaningful difference, but real
production applications showed a reduction in tail latencies of up
to 45%.

When compiling Go programs to WebAssembly, the memory allocation
strategy was neither releasing memory to the OS nor reusing blocks freed
by calls to runtime.sysFreeOS.
This CL unifies the plan9 and wasm memory management strategy
since both platforms use a linear memory space and do not have a
mechanism for returning memory blocks to the OS.

This is a roll-forward of CL 477395 which was rolled back in CL 477736.
The earlier CL failed because we didn't account for the fact that
on some targets PIE is the default. That is now fixed.
