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.

gas/

* config/tc-i386.c (i386_align_code): Limit multi-byte nop
instructions to 10 bytes.
