953f23925f Do NOT inline self recursive calls into other functions. This is causing the 
pool allocator no end of trouble, and doesn't make a lot of sense anyway.  This
does not solve the problem with mutually recursive functions, but they are much less common.

58016b49ef Fix the problem with running cleanups in bugpoint: We were deleting arguments 
of intrinsic functions, causing the verifier to fail.

3e30e40801 Checking in Chris's suggestions: 
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

51684bea99 Make this pass substantially stronger by having it delete dead return values 
as well as arguments.  Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead.  This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.
