hammerCompareAndSwapPointer64 was only passing on
little-endian systems. hammerCompareAndSwapPointer32 was
writing 8 bytes to a uint32 value on the heap.

You could argue for changing all the others, but
Linux is outvoted, and the only time it matters
is when newfd==-1, in which case you can call Dup.

Fixes#2776.
There was a previous attempt at CL 5592043 but that
seems to have stalled. This one is simpler, and more up to date
(correct handling of spdy, for example).

The Date-Modified header truncates sub-second precision, so
use mtime < t+1s instead of mtime <= t to check for unmodified.

Among other things, this avoids putting a testing.go:nnn:
prefix on every line of the stack trace.

Cannot reproduce the failure locally,
but add explicit test in case some other
machine can.

I thought that -timeout was per-test, but it is for the
whole program execution, so cmd/go can adjust its timer
(also for whole program execution) accordingly.

Makes that phase look like all the others.

The paragraph describing the ellipses presents the horizontal ellipsis
in two different fonts and at least on my screen they look too different.
Switch to a consistent rendering.
Of small steps are great journeys undertaken.

Otherwise lockorder may be misaligned, since lockorder is a
list of pointers and pollorder is a list of uint16.
Discovered running gccgo (which uses a modified copy of this
code) on SPARC.

If the values being compared have different concrete types,
then they're clearly unequal without needing to invoke the
actual interface compare routine. This speeds tests for
specific values, like if err == io.EOF, by about 3x.

Fix it twice: reuse registers more aggressively in cgen abop,
and also release R14 and R15, which are no longer m and g.
