We're moving ARC optimisation and ARC emission in clang away from runtime methods
and towards intrinsics. This is the part which actually uses the intrinsics in the ARC
optimizer when both analyzing the existing calls and emitting new ones.

The inline assembly generated for the ARC autorelease elision marker
must have a funclet token if it's emitted inside a funclet, otherwise
the inline assembly (and all subsequent code in the funclet) will be
marked unreachable by WinEHPrepare.
Note that this only applies for the non-O0 case, since at O0, clang
emits the autorelease elision marker itself rather than deferring to the
backend. The fix for clang is handled in a separate change.
