[BOLT] the libhwui.so did not generate prof.fdata in the /tmp directory

I use the following command: /llvm-bolt libhwui.so -instrument --instrumentation-file-append-pid -o libhwui.bolt.so Successfully generated libwhui.bolt.so, and libhwui.bolt.so can run normally.But the libhwui.bolt.so did not generate prof.fdata in the /tmp directory,even though the /tmp directory is writable.If you have any tips, thank you very much!!!

Start by reproducing the reported llvm-bolt command with libhwui.so and the writable /tmp directory, then inspect the instrumentation output and prof.fdata location. Done means the missing prof.fdata behavior is explained and the issue is resolved or its expected behavior is clearly documented.
