[PING] Function versioning and IPCP extension

[Razya Ladelsky <RAZYA at il dot ibm dot com>]

Hello,

This patch implements function versioning and an extension to IPCP that 
supports
the use of versioning, allowing IPCP to analyze all methods in the 
program, 
without any restrictions.

I am attaching a patch which is relative to the previous patch, 
http://gcc.gnu.org/ml/gcc-patches/2005-06/msg01439.html
The first patch will be committed as soon as I change the separation 
of float and integer constants (and other minor changes). 
These changes will be applied to this patch too, of course.

I want to thank Jan Hubicka and Steven Bosscher for their help with 
versioning 
code.

Bootstrap and regression tests successfully passed on Linux PowerPC.

Comments are welcome.

Thanks,
Razya
