  Log Message:
  -----------
  [llvm-exegesis] Do not silently fail on unknown instruction encoding formats.

The addition of TILELOADD instructions with a new encoding format
triggered a hard abort instead of proper error reporting due to the use
of `llvm_unreachable` for actually reachable code.
Properly report an error when the encoding format is unknown.
