Clean up the 2.13.02 release notes: we don't need to list every single
subcase where we would crash, as it is not really relevant to the
user.

For specially formed code we can have skip_white_
to end up with nil pointer which should be taken
into account.

In case if smacro is called with inapropriate
number of arguments exit early. Actually we have
to handle this situation more gracefully but
this requires a way more efforts than two
line patches (need to refactor macro expansion).

For immediates, we had one overflow test in the bytecode interpreter
(in most cases via warn_overflow_opd()) and one in out(); this meant
we got two warnings instead of one every time. Replace with only the
one in out().

The calculation of vmin in overflow_general() was bogus, causing
silliness like ~80h being warned about in a byte context.

We could generate the MRI version (SSE 4.1) instead of the RMI
(SSE 2) version of these instructions if a 64-bit register was given
as the destination.

We need to always define the end symbol, otherwise we might find
ourselves in a situation where the alignment code grows (common!) and
then the symbol is defined late.

The DWARF spec specifies that the .debug_abbrev section always should
end with a null byte. Existing tools don't seem to care, but some
issue a warning, and it is invalid according to spec.

For some output types, the bit size, globalbits, follow the section
(segment); make sure we actually update it!

When using the -MW option, enclose whitespace-containing filenames in
double quotes. There are probably quite a few other things we ought
to know how to do...

We have to consider mode decorators when considering instruction
matching, otherwise we end up falling back to VEX encoding if it is
available, losing the decorator. See BR 3392421.

Use nasm_add_string_to_strlist() to avoid a memory leak.
nasm_add_to_strlist() requires that the caller manages the string
being added or not.
