Limit multi-byte nop instructions to 10 bytes
There is no performance advantage to use multi-byte nop instructions
greater than 10 bytes. This patch limits multi-byte nop instructions
to 10 bytes. Since there is only one way to encode multi-byte nop
instructions now, it also removed redundant nop tests.
