<p><!-- golang.org/issue/38485, golang.org/issue/41385, many CLs -->
Go 1.16 adds support of 64-bit ARM architecture on macOS (also known as
Apple Silicon) with <code>GOOS=darwin</code>, <code>GOARCH=arm64</code>.
Like the <code>darwin/amd64</code> port, the <code>darwin/arm64</code>
port supports cgo, internal and external linking, <code>c-archive</code>,
<code>c-shared</code>, and <code>pie</code> build modes, and the race
detector.
</p>
<p>
The iOS port, which was previously <code>darwin/arm64</code>, is now
moved to <code>ios/arm64</code>. <code>GOOS=ios</code> implies the
<code>darwin</code> build tag, just as <code>GOOS=android</code>
implies the <code>linux</code> build tag.
</p>
<p><!-- golang.org/issue/42100, CL 263798 -->
The <code>ios/amd64</code> port is added, targetting the iOS simulator
running on AMD64-based macOS.
