perf tools: Remove some unused functions

Without the bloated cplus_demangle from binutils, i.e building with:

$ make NO_DEMANGLE=1 O=~acme/git/build/perf -j3 -C tools/perf/ install

Before:

   text	   data	    bss	    dec	    hex	filename
 471851	  29280	4025056	4526187	 45106b	/home/acme/bin/perf

After:

[acme@doppio linux-2.6-tip]$ size ~/bin/perf
   text	   data	    bss	    dec	    hex	filename
 446886	  29232	4008576	4484694	 446e56	/home/acme/bin/perf

So its a 5.3% size reduction in code, but the interesting part is in the git

If we ever need some of the things we got from git but weren't using, we just
have to go to the git repo and get fresh, uptodate source code bits.
