llvm/llvm-isel-fuzzer--aarch64-gisel: ASSERT: isReg() && "This is not a  
register operand!"
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3660#c2

Reproducer in IR:

source_filename = "M"

define void @f() {
BB:
   %A = alloca float
   %G1 = getelementptr float, float* %A, i8 16
   %L1 = load float, float* %G1
   %L = load float, float* %A
   %B2 = fdiv float %L, %L1
   store float %B2, float* %A
   ret void
}
