When running wasm in the browser, the "process" global is not defined.
This causes functions like os.Getpid() to panic, which is unusual.
For example on Windows os.Getpid() returns -1 and does not panic.
This change adds a dummy polyfill for "process" which returns -1 or an
error. It also extends the polyfill for "fs".

Currently cgoCheckPointer is only used with one optional argument.
Using a slice for the optional arguments is quite expensive, hence
replace it with a single interface{}. This results in ~30% improvement.
When checking struct fields, they quite often end up being without
pointers. Check this before calling cgoCheckPointer, which results in
additional ~20% improvement.
Inline some p == nil checks from cgoIsGoPointer which gives
additional ~15% improvement.

The wasm_exec.js wrapper tries to set up the argv and envp following
the UNIX conventions, but doesn't get it quite right, which can cause
runtime.goenv to crash if you get unlucky.
The main problem was that the envp array wasn't terminated with a nil
pointer, so the runtime didn't know when to stop reading the array.
This CL adds that nil pointer to the end of the envp array.
The other problem was harmless, but confusing. In the UNIX convention,
the argv array consists of argc pointers followed by a nil pointer,
followed by the envp array. However, wasm_exec.js put the environment
variable count between the two pointer arrays rather than a nil
pointer. The runtime never looks at this slot, so it didn't matter,
but the break from convention left Cherry and I trying to debug why it
*wasn't* losing any environment variables before we realized that that
layouts happened to be close enough to work. This CL switches to the
UNIX convention of simply terminating the argv array with a nil
pointer.

According to the documentation "When passing a pointer to a field in a
struct, the Go memory in question is the memory occupied by the field,
not the entire struct.". checkAddr states that this should also work
with type conversions, which is implemented in isType. However,
ast.StarExpr must be enclosed in ast.ParenExpr according to the go spec
(see example below), which is not considered in the checks.
Example:
// struct Si { int i; int *p; }; void f(struct I *x) {}
import "C"
type S {
p *int
i C.struct_Si
}
func main() {
v := &S{new(int)}
C.f((*C.struct_I)(&v.i)) // <- panic
}
This example will cause cgo to emit a cgoCheck that checks the whole
struct S instead of just S.i causing the panic "cgo argument has Go
pointer to Go pointer".
This patch fixes this situation by adding support for ast.ParenExpr to
isType and adds a test, that fails without the fix.

The iOS exec wrapper copies the environment variables to the binary
running on the device. However, some variables such as HOME, TMPDIR and
GOCACHE refer to directories that might not be valid on the device.
The wrapper already ignores HOME and TMPDIR, but after GO111MODULE
was flipped to on for the standard library, cmd/go tests started
failing without a valid and writable GOCACHE.
It took a while to reproduce because go test does not set an explicit
GOCACHE but cmd/dist test does.

Now that modules are always on, cmd/go tests require a valid
GOCACHE. However, on iOS where the go tool is not available, the
cmd/go test driver ends up setting GOCACHE to the empty string.
Fix it by falling back to the builtin default cache directory.
The iOS exec wrapper passes the environment variables to the app
on the device, including $HOME used for the default cache directory.
Skip $HOME to let the device specific and writable $HOME be used
instead.
Should fix cmd/go on the iOS builders that broke when GO111MODULE
defaulted to on.

TryBot is sometimes running into deadlocks on js/wasm. We haven't been
able to reproduce them yet. This workaround is an experiment to resolve
these deadlocks by retrying a missed timeout event.
A timeout event is scheduled by Go to be woken by JavaScript after a
certain amount of time. The checkTimeouts function then checks which
notes to wake by comparing their deadline to nanotime. If this
check fails erroneously then the note may stay asleep forever, causing
a deadlock. This may or may not be the reason of the observed
deadlocks.

Android tests are built on the host and run on the device. To do
that, the exec wrapper copies the test binary and testdata to the device.
To enable many more tests, make the copied environment more like the host:
- Copy all of pkg from GOROOT, not just the android pkg directory.
- Copy any parent testdata directories as well as the package's own.
- Copy *.go files from the package directory. This enables misc/cgo/stdio
and misc/cgo/life tests that were invisible before so disable them explicitly.
- Always copy the GOROOT, even for tests outside GOROOT. This is expensive
but only done once per make.bash.
- Build the go tool for the device and put it in PATH. Set GOCACHE
to a writable directory and disable cgo.
While here, use a single directory for all the exec wrapper files and
delete that once per make.bash as well.
In total, this CL enables many tests in the subrepos that would need skips
without it, in particular the x/tools tests.
