I accidentally tried to add a CPU attribute as part of the -mcpu argument
rather than using -mattr, and with the attached trivial program, got the
following crash:

% llc -mcpu=core2+sse41 -march=x86-64 bugpoint-reduced-simplified.bc
'core2+sse41' is not a recognized processor for this target (ignoring
processor)
Assertion failed: (TLI.isTypeLegal(Op.getValueType()) && "Intrinsic uses a
non-legal type?"), function visitTargetIntrinsic, file SelectionDAGBuilder.cpp,
line 3149.
