two new cpu_limits files


(1) IA-64 was missing a file entirely, so __glibcpp_long_bits was incorrect.  

    Actually, even this is incorrect for ia64-hpux.  I'll submit a 
    proposed fix for this momentarily.

(2) The generic Alpha config file has __glibcpp_long_double_bits == 64,
    which is incorrect for Tru64 5.x.

Committed as obvious.


r~


        * config/cpu/ia64/bits/cpu_limits.h: New file.
        * config/os/osf/osf5.0/bits/cpu_limits.h: New file.
        * configure.target (CPULIMITSH): Use them.
