The test in CL 123715 doesn't work on iOS, it needs to use a different
version scheme to determine whether SecKeyAlgorithm and friends exist.
Restrict the old version test to OSX only.
The same problem occurs on iOS: the functions tested don't exist before
iOS 10. But we don't have builders below iOS 10, so it isn't a big issue.
If we ever get older builders, or someone wants to run all.bash on an
old iOS, they'll need to figure out the right incantation.

Two fixes:
1) Typedefs of the bad typedefs should also not be rewritten to the
underlying type. They shouldn't just be uintptr, though, they should
retain the C naming structure. For example, in C:
typedef const __CFString * CFStringRef;
typedef CFStringRef SecKeyAlgorithm;
we want the Go:
type _Ctype_CFStringRef uintptr
type _Ctype_SecKeyAlgorithm = _Ctype_CFStringRef
2) We need more types than just function arguments/return values.
At least we need types of global variables, so when we see a reference to:
extern const SecKeyAlgorithm kSecKeyAlgorithmECDSASignatureDigestX962SHA1;
we know that we need to investigate the type SecKeyAlgorithm.
Might as well just find every typedef and check the badness of all of them.
This requires looping until a fixed point of known types is reached.
Usually it takes just 2 iterations, sometimes 3.

We need to determine whether arguments to and return values from C
functions are "bad" typedef'd pointer types which need to be uintptr
on the Go side.
The type of those arguments are not specified explicitly. As a result,
we never look through the C declarations for the GetTypeID functions
associated with that type, and never realize that they are bad.
However, in another function in the same package there might be an
explicit reference. Then we end up with the declaration being uintptr
in one file and *struct{...} in another file. Badness ensues.
Fix this by doing a 2-pass algorithm. In the first pass, we run as
normal, but record all the argument and result types we see. In the
second pass, we include those argument types also when reading the C
types.

Currently we use a globally unique symbol property on objects that get

approach fails however when a JavaScript object cannot be modified, i.e.
cannot have new properties added or is frozen. The test that is added as
part of this commit currently fails with:
Cannot add property Symbol(), object is not extensible
Instead we consolidate the string, symbol and object unique ID mapping
into a single map. Map key equality is determined via strict equality,
which is the semantic we want in this situation.

Before GCC 8 C code like
const unsigned long long int neg = (const unsigned long long) -1;
void f(void) { static const double x = (neg); }
would get an error "initializer element is not constant". In GCC 8 and
later it does not.
Because a value like neg, above, can not be used as a general integer
constant, this causes cgo to conclude that it is a floating point
constant. The way that cgo handles floating point values then causes
it to get the wrong value for it: 18446744073709551615 rather than -1.
These are of course the same value when converted to int64, but Go
does not permit that kind of conversion for an out-of-range constant.
This CL side-steps the problem by treating floating point constants
with integer type as they would up being treated before GCC 8: as
variables rather than constants.

This commit adds support for JavaScript callbacks back into
WebAssembly. This is experimental API, just like the rest of the
syscall/js package. The time package now also uses this mechanism
to properly support timers without resorting to a busy loop.
JavaScript code can call into the same entry point multiple times.
The new RUN register is used to keep track of the program's
run state. Possible values are: starting, running, paused and exited.
If no goroutine is ready any more, the scheduler can put the
program into the "paused" state and the WebAssembly code will
stop running. When a callback occurs, the JavaScript code puts
the callback data into a queue and then calls into WebAssembly
to allow the Go code to continue running.

When using plugins with goroutines calling cgo, we hit a case where
an intermittent SIGSEGV occurs when referencing an address that is based
on r2 (TOC address). When the failure can be generated in gdb, the
contents of r2 is wrong even though the value in the current stack's
slot for r2 is correct. So that means it somehow switched to start
running the code in this function without passing through the beginning
of the function which had the correct value of r2 and stored it there.
It was noted that in runtime.gogo when the state is restored from
gobuf, r2 is not restored from its slot on the stack. Adding the
instruction to restore r2 prevents the SIGSEGV.
This adds a testcase under testplugin which reproduces the problem if
the program is run multiple times. The team who reported this problem
has verified it fixes the issue on their larger, more complex
application.

The idevicedebugserverproxy command takes a port number without a
flag, like so:
idevicedebugserverproxy 3222
If the -u <device_id> flag is added afterwards, it is ignored and
the command use an arbitrary device. Instead, always inject the -u
flag before any other idevice command arguments.
While here, also kill any leftover idevicedebugserverproxy instance
previous (failed) runs might have left running.

Now that the iOS exec wrapper uninstalls any existing test app before
installing a new, looking up the device app path might fail. Before,
the lookup always succeeded (even though the path reported might be
stale).
For the iOS builder.

Tests can fail because there is leftover data from a previous run.
For example:
--- FAIL: TestRemoveAll (0.00s)
path_test.go:96: RemoveAll "/private/var/mobile/Containers/Data/Application/66247524-5ED7-45A4-82AA-6BF15D6078B2/tmp//_TestRemoveAll_" (first): open /private/var/mobile/Containers/Data/Application/66247524-5ED7-45A4-82AA-6BF15D6078B2/tmp//_TestRemoveAll_/dir: permission denied

There seem to be no way to simply clear the app data for an app
short of uninstalling it, so do that.
This change in effect undoes CL 106676, which means that running iOS
is a little slower again, and that another app from the same
apple developer account must be present on the device for our app
install to succeed.

It turns out that a non-empty result from ideviceimagemounter does
not mean an image is mounted. Use ideviceimagemounter's xml output
mode to improve the check.
Also, iOS versions are reported as major.minor or major.minor.patch.
Developer images are only specific to major.minor version, so cut
off the patch number in the search, if present.

This commit adds the syscall/js package, which is used by the wasm
architecture to access the WebAssembly host environment (and the
operating system through it). Currently, web browsers and Node.js
are supported hosts, which is why the API is based on JavaScript APIs.
There is no common API standardized in the WebAssembly ecosystem yet.
This package is experimental. Its current scope is only to allow
tests to run, but not yet to provide a comprehensive API for users.
Updates #18892

Sometimes, a newly installed the test app is not ready to launch
or the reported app path is stale. Pause and retry the launch if
the lldb script did not run the program.
