  [AArch64] Lower jump table cases threshold to 10

Previous stabs at this setting hypertuned it for SPEC2017, but Clang's
own compilation can benefit from a slightly lower threshold, yielding
a 0.3% improvement in compile time, while still not regressing SPEC.

Most notable benefactors of this change are:
 - llvm::Instruction::getNumSuccessors (11 cases)
 - llvm::Instruction::getSuccessor (11 cases)
