Add a --with-oprofile flag to configure, which uses OProfile's agent

library to tell it the addresses of JITted functions.  For a
particular program, this changes the opreport -l output from:

samples %    image name        symbol name
48182  98.9729 anon (tgid:19412 range:0x7f12ccaab000-0x7f12cdaab000) anon (tgid:19412 range:0x7f12ccaab000-0x7f12cdaab000)

to:
