description:
cpu: remove faulty simpoint basic block inst count assertion
This patch removes an assertion in the simpoint profiling code that
asserts that a previously-seen basic block has the exact same number
of instructions executed as before. This can be false if the basic
block generates aborts or takes interrupts at different locations
within the basic block. The basic block profiling are not affected
significantly as these events are rare in general.
