The SIP debugserver was calling in attach_failed_due_to_sip
haven't worked for a while; remove them. To check this
properly we'd need debugsever to call out to codesign(1) to
inspect the entitlements, or the equivalant API,
and I'm not interested in adding that at this point. SIP
is has been the default on macOS for a couple of releases
and it's expected behavior now.

Starting with iOS 13 simulator binaries are identified with an
explicit platform in the new LC_BUILD_VERSION load command.
On older deployment targets using the LC_VERSION_MIN load commands,
this patch detects when an ios process runs on a macOS host and
updates the target triple with the "simulator" environment
accordingly.
(Patch re-applied with bugfix this time).

The debugserver profile thread used to suspend itself between samples with
a usleep. When you detach or kill, MachProcess::Clear would delay replying
to the incoming packet until pthread_join of the profile thread returned.
If you are unlucky or the suspend delay is long, it could take longer than
the packet timeout for pthread_join to return. Then you would get an error
about detach not succeeding from lldb - even though in fact the detach was
successful...
I replaced the usleep with PThreadEvents entity. Then we just call a timed
WaitForEventBits, and when debugserver wants to stop the profile thread, it
can set the event bit, and the sleep will exit immediately.

LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch
unifies the header guards across LLDB and converts everything to match
LLVM's style.

Look up the -arch flags to pass to the mig invocation from an
optionally-defined MIG_ARCHS variable. We can't use CMAKE_OSX_ARCHS
because the {i,tv,watch}OS builds don't use this mechanism to achieve
fat builds (they build each slice separately & then lipo them together).
This supercedes the mig -arch/-isysroot fix from
510758dae2.
The developer mode check is now working.
Add another check for user id mismatch, e.g. a regular user
trying to attach to something running as root, and describe
the problem for the user.
Explicitly check for a request to attach to a pid that doesn't
exist, to attach to a pid that is already being debugged, unify the
SIP process check, and an attempt at checking if developer mode is
enabled on the system (which isn't working in debugserver, for some
reason; I can't get the authorization record which should be an
unprivileged operation and works in a standalone program I wrote).
I'll debug the developer mode check later, but I wanted to land it
along with everything else; right now it will claim that developer
mode is always enabled so it's harmless to include as-is.
Unify the interface for enabling and disabling breakpoints with their
watchpoint counterpart. This allows both to go through
DoHardwareBreakpointAction.

When launching an inferior in a new terminal window via AppleScript
and the darwin-debug helper program, we could often end up with the
inferior process having a too-high suspend count, and it would never
resume execution.
lldb tries to wait until darwin-debug has finished its work and has
launched the inferior (WaitForProcessToSIGSTOP) but this wasn't
working correctly - and cannot be made to work.
This patch removes WaitForProcessToSIGSTOP, adds a special tiny
segment to the darwin-debug executable so it can be identified as
that binary (ExecExtraSuspend), and adds code to debugserver to
detect this segment. When debugserver sees this segment, it notes
that the next exec will be done with a launch-suspended flag. When
the next exec happens, debugserver forces an extra task_resume when
we resume the inferior.
An alternative approach would be if lldb could detect when the
inferior has been launched by darwin-debug unambiguously; monitoring
when the unix socket between darwin-debug and lldb was closed would
have been a reasonable way to do this too.
