Generate DW_AT_ranges for non-contiguous code

[Sterling Augustine]

This enclosed patch adds support for DW_AT_ranges when assembly code is
noncontiguous. See: http://sourceware.org/ml/gdb/2006-05/msg00015.html
for a discussion of the problem this is addressing.

I believe Tensilica's copyright assignment is already on file.

One issue here is that this particular usage of DW_AT_ranges is dwarf 3,
and gas emits 2 for the dwarf version number. Don't know the right thing 
to do there. Bumping the version number for this seems extreme.

Let me know any issues...

	and emit DW_AT_ranges when code in compilation unit is not
	contiguous.
