Pack ivar offsets together.
...
Ivar offsets for synthesized ivars are wrong, which could end up with a large
number of dirty pages because of ivar fixups at runtime. When we pack all of the
synthesized ivars into the same section, it limits the number of dirty pages
created. Place them in the "__DATA,__objc_ivar" section.

the body of a delegating constructor call.
This means that the delegating constructor implementation should be

quality with the cycle detection and using a deleted destructor).

Devang, can we remove this call entirely? If I try that, "make check" passes
but the call has a side-effect of ensuring that the block's context exists in
the debug info. getContextDescriptor() is used in a void context for that side-
effect elsewhere in this file. Please take a look!
