When code raises an Objective-C exception, unwind the stack looking for
any exception handlers. If an exception handler is encountered, test to
see if it is a function known to be a catch-and-rethrow 'sinkhole'
exception handler. Various routines in UIKit and elsewhere do this, and
they obscure the exception stack, since the original throw location is
no longer present on the stack (just the re-throw) when Crashpad
captures the crash report. In the case of sinkholes, trigger an
immediate exception to capture the original stack.
The is an improvement over the alternative,
NSSetUncaughtExceptionHandler, which passes along the stack frames, but
not the stack memory contents and full exception context itself.
The details of what happens after a fatal exception is triggered are
unresolved in this CL. For now, simply call std::terminate.
This code was inspired by chromium/src/chrome/browser/mac/
exception_processor.mm.

Bionic installs signal handlers which request crash
dumps from Android's debuggerd, but there are errors
in how signals which aren't automatically re-raised
are handled on Marshmallow (API 23).
Before requesting a dump, Bionic acquires a lock to
communicate with debuggerd and expecting imminent
death, never releases it.
While handling the dump request, debuggerd allows
the dying process to continue before
ptrace-detaching it. So, when Bionic manually
re-raises a signal, it is intercepted by debuggerd
and the dying process is allowed to live.
Bionic restores SIG_DFL for the signal it's just
handled, but if a different crash signal is later
recieved, Bionic attempts to reacquire the lock to
communicate with debuggerd and blocks forever.
Disable Bionic's signal handlers for these signals
on Marshmallow.

From cl/304219049:
Optimize C++11 range-based for loops where the variable is copied in
each iteration but it would suffice to obtain it by const reference.
This is only applied to loop variables of types that are expensive to
copy which means they are not trivially copyable or have a non-trivial
copy constructor or destructor.
To ensure that it is safe to replace the copy with a const reference,
the following heuristic is employed:
- The loop variable is const qualified.
- The loop variable is not const, but only const methods or operators
are invoked on it, or it is used as const reference or value argument
in constructors or function calls.

lld wants to remove bl/blx substitution for non-function symbols
(https://reviews.llvm.org/D73542). GNU ld apparently already doesn't
do it.
Since _ZN8crashpad14CaptureContextEP10ucontext_t wasn't marked as a function,
chromium's thumb code would then branch without mode transition into
crashpads non-thumb assembly (in arm32).
So mark the symbol as function, so that things work even if that patch
relands. This should also make things work with GNU ld, though I haven't
verified that it was broken before and works now.
I also did this for aarch64 since it seems like The Right Thing To Do
(assuming the assembler accepts it, which I also haven't checked --
the CQ will hopefully check that).

Using XCTest allows us to drive tests from the commandline via
xcodebuild, and it also simplifies running tests on physical devices.
Tests put themselves into "XCTest-mode" if the
"XCTestConfigurationFilePath" environment variable is present. This
variable is only set when XCTests are running.
