cmd/compilebench: generate separate cpu profiles when using -count

When the -count flag is provided,
instead of having each run overwrite the previous profile,
add a count suffix to the profile filename.
Then you can combine the profiles with

go tool pprof `go tool -n compile` <all profile files here>

This allows generation of precise profiles,
even for fast-compiling packages.
