f52c228416 Implement optimizations for the strchr and llvm.memset library calls. 
Neither of these activated as many times as was hoped:

strchr:
9 MultiSource/Applications/siod
1 MultiSource/Applications/d
2 MultiSource/Prolangs-C/archie-client
1 External/SPEC/CINT2000/176.gcc/176.gcc

llvm.memset:

0c484ea7de 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.

123f4e393f Add the StrNCmpOptimization which is similar to strcmp. 
Unfortunately, this optimization didn't trigger on any llvm-test tests.

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:

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 :)

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).

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)
