This change optimizes the data section in the wasm binary by
omitting blocks of zeroes and instead emitting data segments
with offsets skipping the zeroes.
This optimization is inspired by the memory-packing pass of the
wasm-opt tool and reduces the wasm binary size of "hello world" by 14%.

When gif.Encode is given an "m image.Image" argument that isn't an
*image.Paletted, it creates a temporary *image.Paletted (called pm) that
is intended to be a copy of this image, only with fewer colors.
That creation process, and specifically the opts.Drawer.Draw call that
does the copy, incorrectly assumed that m.Bounds().Min is the zero point
(0, 0). This commit fixes that.

It is possible that a "volatile" value (one that can be clobbered
by preparing args of a call) to be used in multiple write barrier
calls. We used to copy the volatile value right before each call.
But this doesn't work if the value is used the second time, after
the first call where it is already clobbered. Copy it before
emitting any call.

The iOS exec wrapper copies the environment variables to the binary

The wrapper already ignores HOME and TMPDIR, but after GO111MODULE

failing without a valid and writable GOCACHE.
It took a while to reproduce because go test does not set an explicit

To build for watchOS and tvOS the Apple toolchain requires a Mach-O
load command that matches the platform for all object files in a build.
The go.o object file produced by the Go linker contains no such command.
The loader commands are mutually exclusive so we need to pick the
right one. Fortunately, cgo must be enabled for watchOS and tvOS to
be useful, so we can copy the first loader command we find in the object
files produced by the host compiler.
Add a test that builds a small program for tvOS to test both this CL
and the previous CL that added bitcode support.

The original goal of rounding to readable b.N
was to make it easier to eyeball times.
However, proper analysis requires tooling
(such as benchstat) anyway.
Instead, take b.N as it comes.
This will reduce the impact of external noise
such as GC on benchmarks.
This requires reworking our iteration estimates.
We used to calculate the estimated ns/op
and then divide our target ns by that estimate.
However, this order of operations was destructive
when the ns/op was very small; rounding could
hide almost an order of magnitude of variation.
Instead, multiply first, then divide.
Also, make n an int64 to avoid overflow.
Prior to this change, we attempted to cap b.N at 1e9.
Due to rounding up, it was possible to get b.N as high as 2e9.
This change consistently enforces the 1e9 cap.
This change also reduces the wall time required to run benchmarks.
Here's the impact of this change on the wall time to run
all benchmarks once with benchtime=1s on some std packages:
name old time/op new time/op delta
bytes 306s ± 1% 238s ± 1% -22.24% (p=0.000 n=10+10)

This is part of a general effort to shrink walk.
In an ideal world, we'd have an SSA op for allocation,
but we don't yet have a good mechanism for introducing
function calling during SSA compilation.
In the meantime, SSA conversion is a better place for it.
This also makes it easier to introduce new optimizations;
instead of doing the typecheck walk dance,
we can simply write what we want the backend to do.
I introduced a new opcode in this change because:
(a) It avoids a class of bugs involving correctly detecting
whether this ONEW is a "before walk" ONEW or an "after walk" ONEW.
It also means that using ONEW or ONEWOBJ in the wrong context
will generally result in a faster failure.
(b) Opcodes are cheap.
(c) It provides a better place to put documentation.
This change also is also marginally more performant:
