This defines a macro for the regabi GOEXPERIMENT when assembling
runtime assembly code.
In general, assembly code will be shielded from the calling convention
change, but there is a small amount of runtime assembly that is going
to have to change. By defining a macro, we can easily make the small
necessary changes. The other option is to use build tags, but that
would require duplicating nontrivial amounts of unaffected code,
leading to potential divergence issues. (And unlike Go code, assembly
code can't depend on the compiler optimizing away branches on a
feature constant.) We consider the macro preferable, especially since
this is expected to be temporary as we transition to the new calling
convention.

While debugging #40771, I realized that the chatty printer should only
ever print to a single io.Writer (normally os.Stdout). The other
Writer implementations in the chain write to local buffers, but if we
wrote a test's output to a local buffer, then we did *not* write it to
stdout and we should not store it as the most recently logged test.
Because the chatty printer should only ever print to one place, it
shouldn't receive an io.Writer as an argument — rather, it shouldn't
be used at all for destinations other than the main output stream.
On the other hand, when we flush the output buffer to stdout in the
top-level flushToParent call, it is important that we not allow some
other test's output to intrude between the test summary header and the
remainder of the test's output. cmd/test2json doesn't know how to
parse such an intrusion, and it's confusing to humans too.
No test because I couldn't reproduce the user-reported error without
modifying the testing package. (This behavior seems to be very
sensitive to output size and/or goroutine scheduling.)

Rather than probe and guess if sendfile will work inside ResponseWriter.ReadFrom(src),
this change fixes the underlying issue of starting to respond before src is readable
We'll no longer send a status OK if a header has not yet been written and reading
from src is destined to fail. This small change implicitly takes care of the need for
the server to sniff the response body to determine the Content-Type.
This allows splice to work on Linux when src is a socket or any non-regular file that's spliceable.
The extra read of 512 bytes may raise an objection, and that's fair, but
we're already swapping some syscall prep work for another and a read of
512 probably will not impact the overall performance. For shorter

CL 195679 added further support for relocations, but explicitly encoded

This change removes that assumption: all relocations will now be
properly computed based on the target symbol value even when that symbol

Typically, sections that are part of a LOAD program segment have
non-zero addresses. For example, .debug_ranges relocations could be
