libfuzzer is written in C and so requires by the C abi that SP be aligned correctly mod 16. Normally CALLs need to have SP aligned to 0 mod 16, but because we're simulating a CALL (which pushes a return address) with a JMP (which doesn't), we need to align to 8 mod 16 before JMPing. This is not causing any current problems that I know of. All the functions called from this callsite that I checked don't rely on correct alignment. So this CL is just futureproofing.
