According to the timeline view, sqrtss/sd/rcpss start executing before the load
address for the memory operand is available.
This problem is caused by the presence of a ReadAfterLd (a ReadAdvance). Those
unary operations should not specify a ReadAdvance at all.

[XRay] FDR Record Producer/Consumer Implementation
Summary:
This patch defines two new base types called `RecordProducer` and
`RecordConsumer` which have default implementations for convenience
(particularly for testing).
A `RecordProducer` implementation has one member function called
`produce()` which serves as a factory constructor for `Record`
instances. This code exercises the `RecordInitializer` code path in the
implementation for `FileBasedRecordProducer`.
A `RecordConsumer` has a single member function called `consume(...)`
which, as the name implies, consumes instances of
`std::unique_ptr<Record>`. We have two implementations, one of which is
used in the test to generate a vector of `std::unique_ptr<Record>`
similar to how the `LogBuilder` implementation works.
We introduce a test in `FDRProducerConsumerTest` which ensures that
records we write through the `FDRTraceWriter` can be loaded by the
`FileBasedRecordProducer`. The record(s) loaded this way are written
again through the `FDRTraceWriter` into a separate string, which we then
compare. This ensures that the read-in bytes to create the `Record`
instances in memory can be replicated when written out through the
`FDRTraceWriter`.
This change depends on D51210 and is part of the refactoring of D50441
into smaller, more focused changes.
