Yevgeny Rouban cb87f3734b Force check prof branch_weights consistency in SwitchInstProfUpdateWrapper ...

This patch turns on the prof branch_weights metadata consistency
check in SwitchInstProfUpdateWrapper.

If this patch causes a failure then please before reverting do report
the IR that hits the assertion and try identifying the pass that
introduces the inconsistency. We have to fix all such passes.
