Previously, mismatches in opcode or number of operands wasn't very informative
because the error message didn't print out the HloInstruction string. For
example, an opcode mismatch might have looked like previously:
Value of: body_data_add
Expected: subtract
Actual: 0x7f58fe3e8c00 (of type xla::HloInstruction*)
With this CL, it now looks like:
Value of: body_data_add
Expected: subtract
Actual: 0x7efefd68ec00 (of type xla::HloInstruction*), (%add.1 = f32[2,3]{1,0:S(1)} add(f32[2,3]{1,0} %get-tuple-element.2, f32[2,3]{1,0} %constant.2))
