When If-Range does not match and the requested resource is
available, server should return a "200 OK" response to client.
Currently server returns "200 OK" when the request method is
GET, but "206 Partial Content" when method is HEAD.
This change fixed this inconsistency.

SkipNow and FailNow must be called from the goroutine running the
test. This is already documented, but it's easy to call them by
mistake when writing subtests. In the following:
func TestPanic(t *testing.T) {
t.Run("", func(t2 *testing.T) {
t.FailNow() // BAD: should be t2.FailNow()
})
}
the FailNow call on the outer t *testing.T correctly triggers a panic
panic: test executed panic(nil) or runtime.Goexit
The error message confuses users (see issues #17421, #21175) because
there is no way to trace back the relevant part of the message ("test
executed ... runtime.Goexit") to a bad FailNow call without checking
the testing package source code and finding out that FailNow calls
runtime.Goexit.
To help users debug the panic message, mention in the SkipNow and
FailNow documentation that they stop execution by calling
runtime.Goexit.
Fixes#21175

The only non test user of the assembler prefetch functions is the
heapBits.prefetch function which is itself unused.
The runtime prefetch functions have no functionality on most platforms
and are not inlineable since they are written in assembler. The function
call overhead eliminates the performance gains that could be achieved with
prefetching and would degrade performance for platforms where the functions
are no-ops.
If prefetch functions are needed back again later they can be improved
by avoiding the function call overhead and implementing them as intrinsics.

Setting the Content-Type header explicitly allows browsers to know what
the type of the content is. Otherwise, they have to guess the type from
the content itself, which could lead to unpredictable behavior, and
increases CPU usage.
Not setting the Content-Type despite writing a body may also trigger
unwanted warnings in user middleware, and make it more difficult to
resolve valid issues where the user forgets to set Content-Type in
some situations where it should be set.
There is some precedent for doing this in http.FileServer, which
sets "Content-Type" to "text/html; charset=utf-8" before writing
<pre><a href=...></a></pre> HTML.
