--- Comment #1 from Matt Davis <matthew.davis at sony.com> ---
Closing this feature out:

* Error propagation was introduced in https://reviews.llvm.org/D50561
* Code landed in r339594: https://reviews.llvm.org/rL339594

In summary: The patch communicates error states from within InstrBuilder and
RegisterFile (llvm-mca library classes) up to the driver.  This removes
premature exits from the library, and lets the driver make the decision as to
exit or not.
