`release-nonlto` build produces binaries with performance close to
`--release` build, but compiles faster. This compilation profile is used for
easier development and benchmarking.
Now it by default strips the debug symbols, as a consequence, If a
flamegraph is collected using this `release-nonlto` build, useful function
names will not displayed.
### Reproducer:
`sudo cargo flamegraph --profile release-nonlto --bin dfbench -- sort-tpch
-p /Users/yongting/Code/datafusion/benchmarks/data/tpch_sf10 -q 3`
The generated flamegraph will look like:
If we keep the symbol names, the flamegraph will be generated with function
names in the call stack.
