llc < bugpoint-reduced-simplified.bc
PromoteIntegerOperand Op #1: 0x18084d4: i32 = shl 0x180822c, 0x180844c
Assertion failed: (0 && "Do not know how to promote this operator's operand!"),
function PromoteIntegerOperand, file LegalizeIntegerTypes.cpp, line 584.

This is reduced from a case in the gcc testsuite (ppc32 Darwin).  Apparently
came in with LegalizeTypes.
