431ff0756a avr: Fix bugs in org/align tracking.
This commit fixes a few issues in the mechanism for passing information
about ".org" and ".align" directives from the assembler to the linker,
used by the avr target.

In the original commit fdd410ac7a, there
were some mistakes when writing out information about ".align"
directives:
  - An align with fill does not write out its information correctly, the
    fill data overwrites the alignment data.
  - Each alignment directive is recorded at the location where the
    previous alignment directive should be recorded, the first alignment
    directive is discarded.

In commit 137c83d69f, the data produced by
objdump is not correct:
   - It's miss-aligned due to a missing whitespace.
   - The fill data for align with fill records is not displayed
     correctly.

All of the above issues are addressed in this commit, and the test is
improved to cover these cases.

binutils/ChangeLog:

	* od-elf32_avr.c (elf32_avr_dump_avr_prop): Fix printing of align
	specific data, fix formatting for align and org data.

gas/ChangeLog:

	* config/tc-avr.c (avr_output_property_record): Fix overwrite bug
	for align and fill records.
	(avr_handle_align): Record fill information for align frags.
	(create_record_for_frag): Add next frag assertion, use correct
	address for align records.

gas/testsuite/ChangeLog:

	* gas/avr/avr-prop-1.s: Use fill in some cases.
	* gas/avr/avr-prop-1.d: Update expected results.
