80b8656cba 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.

fdd410ac7a avr/gas: Write out data to track .org/.align usage.
Adds support to the assembler to write out data for tracking the use of
.org and .align directives.  This data is collected within the assembler
and written out to a section ".avr.prop" (if there's anything to write
out).

This patch does not add any tests.  The next patch in this series will
add a better mechanism for visualising the contents of .avr.prop which
will make writing tests much easier.

This patch also does not make any use of this collected data, that will
also come along in a later patch; the intended consumer is the linker,
during linker relaxation this information will be used to ensure that
the .org and .align directives are honoured.

64a81db054 Fix msp430 build with gcc-5
gcc-5 correctly complains "loop exit may only be reached after
undefined behavior".  I was going to correct this by checking the
index before dereferencing the array rather than the other way around,
but then I noticed it is possible for extract_cmd to write the
terminating zero one past the end of "cmd".  Fixing that means no
index check is needed in md_assemble.

	* config/tc-msp430.c (md_assemble): Correct size passed to
	extract_cmd.  Remove index check.
