a5fcd1660f 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:

1e1117ed7a Remove support for 1.0 style varargs 
amusing of course, because we will have to go back to those semantics soon

4d9c8f8dce support multiplication by constant negative integers 
this constmul code is still buggy though, so beware. mul by 7427 is currently
broken, for example. will fix it when I get a moment :)

7a185a79a5 add support for bools to SELECT, this fixes Prolangs-C/bison from the 
testsuite, however 09-vor is still dead (hopefully for other reasons!)

425f215095 Fixed bug in searchPath function for finding nodes between two recurrences. 
Changed dependence analyzer to only use dep distances of 2 or less.
This is experimental.

Changed MSchedGraph to be able to represent more then one BB (first steps).

936709ad19 I was sure I had thought about this and there was a reason it should work. 
But it is entirely possible I am just crazy.

cc551c4345 * Don't depend on "guessing" what a FILE* is, just require that the actual 
type be obtained from a CallInst we're optimizing.
* Make it possible for getConstantStringLength to return the ConstantArray
  that it extracts in case the content is needed by an Optimization.
* Implement the strcmp optimization
* Implement the toascii optimization

This pass is now firing several to many times in the following MultiSource
tests:

Applications/Burg      -   7 (strcat,strcpy)
Applications/siod      -  13 (strcat,strcpy,strlen)
Applications/spiff     - 120 (exit,fputs,strcat,strcpy,strlen)
Applications/treecc    -  66 (exit,fputs,strcat,strcpy)
Applications/kimwitu++ -  34 (strcmp,strcpy,strlen)
Applications/SPASS     - 588 (exit,fputs,strcat,strcpy,strlen)
