[IRPGO] instrumentation for multiple .so but one profile file generated

[sig-loha-huang]

hi，
In -fprofile-continuous mode or -fprofile-generate=libxx_%p%c, when performing IR-PGO instrumentation for multiple .so files or ELF executable binaries, only one profile file is actually generated after execution.
Does LLVM PGO instrumentation have functionality similar to llvm-bolt's -instrumentation-sleep-time=3?
