This reverts commit a631daba5f.
Reason for revert: I was wrong. It still fails on the builders.
I don't know what's different about my VMWare VM, but on GCE it fails.

The fix (CL 79575) for #18395 is too risky at this stage of the Go 1.10
release process.
Since issue #18395 is easily recognized (but not easily fixed), report
an error instead of silently continuing. This avoids inscrutable follow
on errors.
Also, make sure all empty interfaces are "completed", and adjust
printing code to report incomplete interfaces.
For #18395.

Several usages of tar (reasonably) just use the Header.FileInfo
to determine the type of the header. However, the os.FileMode type
is not expressive enough to represent "files" that are not files
at all, but some form of metadata.
Thus, Header{Typeflag: TypeXGlobalHeader}.FileInfo().Mode().IsRegular()
reports true, even though the expected result may have been false.
To reduce (not eliminate) the possibility of failure for such usages,
use the placeholder filename from the global PAX headers.
Thus, in the event the user did not handle special "meta" headers
specifically, they will just be written to disk as a regular file.
As an example use case, the "git archive --format=tgz" command produces
an archive where the first "file" is a global PAX header with the
name "global_pax_header". For users that do not explicitly check
the Header.Typeflag field to ignore such headers, they may end up
extracting a file named "global_pax_header". While it is a bogus file,
it at least does not stop the extraction process.

In order to avoid a regression where the date of the ModTime method
changed behavior, simply preserve the old behavior of determining
the date based on the legacy fields.
This ensures that anyone relying on ModTime before Go1.10 will have
the exact same behavior as before.
New users should use FileHeader.Modified instead.
We keep the UTC coersion logic in SetModTime since some users
manually compute timezone offsets in order to have precise control
over the MS-DOS time field.

Panic if an http Handler does:
rw.WriteHeader(0)
... or other invalid values. (for a forgiving range of valid)
I previously made it kinda work in https://golang.org/cl/19130 but
there's no good way to fake it in HTTP/2, and we want HTTP/1 and
HTTP/2 behavior to be the same, regardless of what programs do.
Currently HTTP/2 omitted the :status header altogether, which was a
protocol violation. In fixing that, I found CL 19130 added a test
about bogus WriteHeader values with the comment:
// This might change at some point, but not yet in Go 1.6.
This now changes. Time to be strict.

Previously, golang.org/cl/75350 updated ReadMIMEHeader to ignore the
first header line when it begins with a leading space, as in the
following example:
GET / HTTP/1.1
Host: foo.com
Accept-Encoding: gzip
However, golang.org/cl/75350 changed ReadMIMEHeader's behavior for the
following example: before the CL it returned an error, but after the
CL it ignored the first line.
GET / HTTP/1.1
Host foo.com
Accept-Encoding: gzip
This change updates ReadMIMEHeader to always fail when the first header
line starts with a space. During the discussion for golang.org/cl/75350,
we realized we had three competing needs:
1. HTTP clients should accept malformed response headers when possible
(ignoring the malformed lines).
2. HTTP servers should reject all malformed request headers.
3. The net/textproto package is used by multiple protocols (most notably,
HTTP and SMTP) which have slightly different parsing semantics. This
complicates changes to net/textproto.
We weren't sure how to best fix net/textproto without an API change, but
it is too late for API changes in Go 1.10. We decided to ignore initial
lines that begin with spaces, thinking that would have the least impact on
existing users -- malformed headers would continue to parse, but the
initial lines would be ignored. Instead, golang.org/cl/75350 actually
changed ReadMIMEHeader to succeed in cases where it previously failed
(as in the above example).
Reconsidering the above two examples, there does not seem to be a good
argument to silently ignore ` Host: foo.com` but fail on ` Host foo.com`.
Hence, this change fails for *all* headers where the initial line begins
with a space.

The comment for phase 2 of checker.interfaceType (typexpr.go:517)
requires that embedded interfaces be complete for correctness of
the algorithm.
Yet, the very next comment (typexpr.go:530) states that underlying
embedded interfaces may in fact be incomplete.
This is in fact the case and the underlying bug in issue #18395.
This change makes sure that new interface types are marked complete
when finished (per the implicit definition in Interface.Complete,
type.go:302). It also adds a check, enabled in debug mode only, to
detect the use of incomplete embedded interfaces during construction
of a new interface. In debug mode, this check fails for the testcase
in the issue (and several others).
This change has no noticeable impact with debug mode disabled.
For #18395.

And as described in the C99 standard which is claimed as the original cephes source.
Sqrt did not return the correct branch when imag(x) == 0. The branch is now
determined by sign(imag(x)). This incorrect branch choice was affecting the behavior
of the Trigonometric/Hyperbolic functions that use Sqrt in intermediate calculations.
Asin, Asinh and Atan had spurious domain checks, whereas the functions should be valid
