9974ddab2b Avoid garbage output in the statistics display by ensuring that the
strings passed to Statistic's constructor are not destructable. The stats
are printed during static destruction and the SimplifyLibCalls module was
getting destructed before the statistics.

a1b4390938 Implement the fprintf optimization which converts calls like this:
fprintf(F,"hello") -> fwrite("hello",strlen("hello"),1,F)
  fprintf(F,"%s","hello") -> fwrite("hello",strlen("hello"),1,F)
  fprintf(F,"%c",'x') -> fputc('c',F)

This optimization fires severals times in llvm-test:

broken, for example. will fix it when I get a moment :)
