the locals and arguments liveness maps for a frame, plus a third

Using the extendslice init node list to add the init nodes for the memclr
call could add init nodes for memclr function before the growslice call
created by extendslice.
As all arguments of the memclr were explicitly set in OAS nodes before
the memclr call this does not change the generated code currently.
./all.bash runs fine when replacing memclr init with nil suggesting there
are currently no additional nodes added to the init of extendslice by
the memclr call.
Add the init nodes for the memclr call directly before the node of the
memclr call to prevent additional future init nodes for function calls
and argument evaluations to be evaluated too early when other compiler
code is added.

When running tests that fails to complete within the test timeout,
the go tool sends the test program a SIGQUIT signal to print
backtraces. However, for tests running with an exec wrapper, the
resulting backtraces will come from the exec wrapper process and
not the test program.
Change the iOS exec wrapper to forward SIGQUIT signals to the lldb
python driver and change the driver to forward the signals to the
running test on the device.

To date, go run has required a list of .go files.
This CL allows in place of that list a single import path
or a directory name or a pattern matching a single patckage.
This allows 'go run pkg' or 'go run dir', most importantly 'go run .'.
The discussion in #22726 gives more motivation.
The basic idea is that you can already run 'go test .'
but if you're developing a command it's pretty awkward
to iterate at the same speed. This lets you do that,
by using 'go run . [args]'.

Move ops can be faster than memmove calls because the number of bytes
to be moved is fixed and they don't incur the overhead of a call.
This change allows memmove to be converted into a Move op when the
arguments are disjoint.
The optimization is only enabled on s390x at the moment, however
other architectures may also benefit from it in the future. The
memmove inlining rule triggers an extra 12 times when compiling the
standard library. It will most likely make more of a difference as the
disjoint function is improved over time (to recognize fresh heap
allocations for example).

This test runs independent goroutines modifying a comprehensive variety
of local vars to look for garbage collector regressions. This test has
been verified to trigger issue 22781 on the go1.9.2 tag. This test
expands on test/fixedbugs/issue22781.go.

replace map clears of the form:
for k := range m {
delete(m, k)
}
(where m is map with key type that is reflexive for ==)
with a new runtime function that clears the maps backing
array with a memclr and reinitializes the hmap struct.
Map key types that for example contain floats are not
replaced by this optimization since NaN keys cannot
be deleted from maps using delete.

The phrase "couple X" is considered colloquial, so make that "a couple of X".
Also move the start of a sentence to a new line in a couple of places
for easier editing, in one place thereby removing two spaces after a period.

The videos on the front page are always the same width, regardless of
the viewport width. These changes let the video fill the space given
to its container regardless of layout. It uses the standard hack for
making iframes responsive, but the videos are loaded at random and do
not have uniform aspect ratios so that information is injected into the
DOM using custom properties. If these are not supported, it falls back
to the same layout present before this change.
Note: this change also requires CL 108678 to complete the fix,
though either CL without the other is harmless.
Updates #24997.

Some *mem ops are loads, some are stores, some are modifications.
Replace mem->load for the loads.
Replace mem->store for the stores.
Replace mem->modify for the load-modify-stores.
The only semantic change in this CL is to mark
ADD(Q|L)constmodify (which used to be ADD(Q|L)constmem) as
both a read and a write, instead of just a write. This is arguably
a bug fix, but the bug isn't triggerable at the moment, see CL 112157.
