[pushed] Objective-C/C++: Ensure sufficient setup for the preprocessor.
Checks
Commit Message
This is a regression fix where non-trivial Objective-C parses would
ICE when given -save-temps (ICE in the lexer).
This is a short-term fix for stage-4. ISTM that we should not really
be making use of these functions in lexing and hopefully in GCC-15
we can take a look at moving the functionality to a later phase.
Tested on i686, powerpc, x86_64 Darwin, x86_64 Linux, pushed to trunk,
thanks

The tokenizer makes use of functions that determine if identifiers
are interface or class names, and those functions need a hash map
to be set up.
This ensures that these are initialized before pre-process-only
jobs are run.
gcc/objc/ChangeLog:
* objc-act.cc (objc_init): Initialize interface and class
name hash maps before the preprocessor uses them.
