testcase

ClamAV failed to build for ARM last night.  This is a bugpoint-reduced
testcase.  Compile it with:

llc -O3 -relocation-model=pic -mcpu=arm1136jf-s -f
bugpoint-reduced-simplified.bc

Assertion failed: ((DstRC || (TID.isVariadic() && IIOpNum >=
TID.getNumOperands())) && "Don't have operand info for this instruction!"),
