[InstrProf] Fix BalancedPartitioning when threads are disabled
In https://reviews.llvm.org/D147812 we introduced the class
`BalancedPartitioning` which includes some threading code. The tests in
that diff run forever when built with `-DLLVM_ENABLE_THREADS=OFF` so
some bots were broken.
These tests were skipped in
https://reviews.llvm.org/rGa4845eaf2e9aa18dd900d7cbeff4e5ff52e4b50e
because of this.
This diff disables the threading code if `LLVM_ENABLE_THREADS` is
disabled so we can re-enable the tests.

[InstrProf] Move BPFunctionNode test to ProfileDataTests
In https://reviews.llvm.org/D147812 I created
`BalancedPartitioningTest.cpp` and inadvertently drastically increased the
number of files needed to compile `SupportTests`. Instead lets move the
`BPFunctionNode` test to `unittests/ProfileData` so we can remove the
extra dependency.

[InstrProf] Use BalancedPartitioning to order temporal profiling trace data
In [0] we described an algorithm called //BalancedPartitioning// (bp) to consume function traces [1] and compute a function order that reduces the number of page faults during startup.
This patch adds the `order` command to the `llvm-profdata` tool which uses bp to output a function order that can be passed to the linker via `--symbol-ordering-file=`.
Special thanks to Sergey Pupyrev and Julian Mestre for designing this balanced partitioning algorithm.
