1eb9e6cc47 Fix "unimplemented features": 
test/Regression/Transforms/FunctionResolve/retmismatch[12].ll

This makes it much more useful for running benchmarks that are missing
prototypes for some functions.

e3da2980ad Support programs that do not #include <malloc.h> or give a full prototype 
for malloc and free.  Lots of crufty benchmarks are using stuff like:
char *malloc();
void free();

to forward declare malloc and free.  Now we recognize and raise these forms

47f37c3404 Hash pointer values to a sequence number to get identical results from 
lli and llc.  This is controlled with options -tracehash on|off.

Also, added an option to specify which functions should be traced.
Particularly useful to reduce output volume in basic-block tracing.

7bc532dded * Make debug output conditional on #define 
* Add optimization to rank computation to not recursively search when
  unneccesary.
* More agressively negate expressions to open reassociation opportunities.
* Linearize (A+B)+(C+D) into ((A+B)+C)+D

are backwards, but swappable.

053c0939e3 Fix bug: test/Regression/Transforms/InstCombine/2002-05-14-TouchDeletedInst.ll 
"This testcase caused instcombine to fail because it got the same instruction on
it's worklist more than once (which is ok), but then deleted the instruction.
Since the inst stayed on the worklist, as soon as it came back up to be
processed, bad things happened, and opt asserted."

a3c3456e7f Fix a major source of "type unsafety", where a cast is neccesary, but can 
be put either before or after a load.  We chose to cast the value loaded
instead of the pointer to load from.

Fixes bug: test/Regression/Transforms/LevelRaise/2002-05-10-LoadPeephole.ll

da2eddd5c4 * Add support for the -stats command line option to report how much is changed 
* Make cast-of-self-ty DCE the dead cast instruction immediately instead of
  waiting for it to be DCE'd by another sweep over the function.  This speeds
  this up noticably.
