Andi Kleen 3b0b16bf8c perf tools: Support --prefix/--prefix-strip 
The objdump utility has useful --prefix / --prefix-strip options to
allow changing source code file names hardcoded into executables' debug
info. Add options to 'perf report', 'perf top' and 'perf annotate',
which are then passed to objdump.

  $ mkdir foo
  $ echo 'main() { for (;;); }' > foo/foo.c
  $ gcc -g foo/foo.c
  foo/foo.c:1:1: warning: return type defaults to ‘int’ [-Wimplicit-int]
      1 | main() { for (;;); }
        | ^~~~
  $ perf record ./a.out
  ^C[ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.230 MB perf.data (5721 samples) ]
  $ mv foo bar
  $ perf annotate
  <does not show source code>
  $ perf annotate --prefix=/home/ak/lsrc/git/bar --prefix-strip=5
  <does show source code>
