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
