aubinator: Make gen_disasm_disassemble handle split sends

Skylake adds new SENDS and SENDSC opcodes, which should be
handled in the send-with-EOT check. Make an is_send() helper
that checks if the opcode is SEND/SENDC/SENDS/SENDSC (Ken)

v2: Make is_send() much more crispier, Mix declaration and
code to make the code compact (Ken)
