Testcase for Irix6 chill bootstrap failures -gdwarf-2 related

[Kaveh R. Ghazi]

Regarding the mips bootstrap failures in the chill directory, I've
reduced the following testcase from gcc/ch/hash.c which is a gperf
generated file.

Compiling it on mips-sgi-irix6.2 with "-g -O2" or on i686-pc-linux-gnu
with "-g -O2 -gdwarf-2" causes a SEGV.  It also happens at -O1, and I
think the __inline keyword is necessary.

(This should probably be in the testsuite.)

      MIN_WORD_LENGTH = 2,
      MAX_WORD_LENGTH = 30,

      MAX_HASH_VALUE = 2821
    };
 
  return 0;
