This adds saving/restoring CPP macros, and validity checking of the

Bootstrapped & tested on x86-linux.
In cpp_write_pch() writing
- list of identifiers that are not defined
- list of identifiers that are defined
But in cpp_valid_pch() while validating you are reading
- list of identifiers that must be defined
- list of identifiers that must not be defined
The ordering between writing and reading does not seem consistent
to me. Or am I missing something?
