[PATCH] AArch64: Relax assert about large shift sizes.

[Matthias Braun]

The radar mentions "llvm-stress --seed=29856" as the source of that program, maybe that just doesn't perform any combining/constant folding. In each case I don't know if we should always rely on constant folding/combining happening, what is with clang -O0 for example?
In any case having an instruction with an undefined result in the IR is no reason for a target to fail an assertion IMO.
