When writing a PCH file, write multiple type and declaration blocks as
...
necessary and iterate until all types and declarations have been
written. This reduces the Cocoa.h PCH file size by about 4% (since we
don't write types we don't need), and fixes problems where writing a
declaration generates a new type.
This doesn't seem to have any impact on performance either way.

Don't read all of the records in the PCH file's preprocessor block,
...
most of which are ignored. Instead, move the __COUNTER__ value out to
a PCH-level record (since it is handled eagerly) and move the header
file information into the SourceManager block (which is also,
currently, loaded eagerly).
This results in another 17% performance improvement in the
Cocoa-prefixed "Hello, World" with PCH.
