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'

8 years ago[PM] Provide two templates for the two directionalities of analysis
Chandler Carruth [Sat, 27 Feb 2016 10:38:10 +0000 (10:38 +0000)]
[PM] Provide two templates for the two directionalities of analysis
manager proxies and use those rather than repeating their definition
four times.

There are real differences between the two directions: outer AMs are
const and don't need to have invalidation tracked. But every proxy in
a particular direction is identical except for the analysis manager type
and the IR unit they proxy into. This makes them prime candidates for
nice templates.

I've started introducing explicit template instantiation declarations
and definitions as well because we really shouldn't be emitting all this
everywhere. I'm going to go back and add the same for the other
templates like this in a follow-up patch.

I've left the analysis manager as an opaque type rather than using two
IR units and requiring it to be an AnalysisManager template
specialization. I think its important that users retain the ability to
provide their own custom analysis management layer and provided it has
the appropriate API everything should Just Work.

[LICM] Teach LICM how to handle cases where the alias set tracker was

The fix is very isolated, but I've pulled the code for merging blocks
