[PM] Wire up optimization levels and default pipeline construction APIs
in the PassBuilder.

These are really just stubs for now, but they give a nice API surface
that Clang or other tools can start learning about and enabling for
experimentation.

I've also wired up parsing various synthetic module pass names to
generate these set pipelines. This allows the pipelines to be combined
with other passes and have their order controlled, with clear separation
between the *kind* of canned pipeline, and the *level* of optimization
to be used within that canned pipeline.

The most interesting part of this patch is almost certainly the spec for
the different optimization levels. I don't think we can ever have hard
and fast rules that would make it easy to determine whether a particular
optimization makes sense at a particular level -- it will always be in
large part a judgement call. But hopefully this will outline the
expected rationale that should be used, and the direction that the
pipelines should be taken. Much of this was based on a long llvm-dev
discussion I started years ago to try and crystalize the intent behind
these pipelines, and now, at long long last I'm returning to the task of
actually writing it down somewhere that we can cite and try to be
consistent with.

[UBSan] Fix isDerivedFromAtOffset on iOS ARM64

Summary:
iOS on ARM64 doesn't unique RTTI.
Ref: clang's iOS64CXXABI::shouldRTTIBeUnique()

Due to this, pointer-equality will not necessarily work in this
architecture, across dylib boundaries.

dynamic_cast<>() will (as expected) still work, since Apple ships with
one prepared for this, but we can't rely on the type names being
pointer-equal.

I've limited the expensive strcmp check to the specific architecture
which needs it.

Example which triggers this bug:

lib.h:
  struct X {
    virtual ~X() {}
  };
  X *libCall();

lib.mm:
  X *libCall() {
    return new X;
  }

prog.mm:
  int main() {
    X *px = libCall();
    delete px;
  }

Expected output: Nothing
Actual output:
<unknown>: runtime error: member call on address 0x00017001ef50 which does not point to an object of type 'X'

a particular direction is identical except for the analysis manager type

nice templates.

everywhere. I'm going to go back and add the same for the other

the appropriate API everything should Just Work.
