Florian Hahn b156528748 [AArch64] support neon_sshl and neon_ushl in performIntrinsicCombine.
Try to generate ushll/sshll for aarch64_neon_ushl/aarch64_neon_sshl,
if their first operand is extended and the second operand is a constant

Also adds a few tests marked with FIXME, where we can further increase
codegen.
