This is the null implementation of the function debug_directive. For
some reason it ended up getting mangled as "null_debug_routine".

At moment we can't overrun buffer even if we would like to
but better to stay on a safe side and use snprintf.

If [DEBUG id] has id longer then 80 symbols (well, 79 actually plus
EOS) then stack will be just overwritten.
Fix it with explicit check for identifier being too long.

Convert Intel AVX instructions to explisit size
format. Part 2.
Also CLMUL converted as well.
Btw, VPINSR was a bit broken since SB constraint
is not applied on all forms but requires 16,32,64
memory sizes too. Fixed.

"Optimise" (and other -ise words) is en_GB, "optimize" (and other
"-ize" words) is en_US. Stick to en_US since that is what we seens to
be using more already.

Note that we use list_for_each(var,var) sometime
which actually brings in at least one redundant
assignment in case of NULL being passed but save
us a few lines of code.

Clear an uninitialized variable warning. The case can't actually
happen, but the compiler doesn't know that.

The construct:
if (i == nsects)
directive_sec =
sects[coff_make_section
(EXPORT_SECTION_NAME, EXPORT_SECTION_FLAGS)];
... where coff_make_section() can change the global variable "sects"
is undefined C, since there is no sequence point involved in the []
operator, and it is therefore fully permitted for the C compiler to
read the sects variable first. Change this construct into two
statements to enforce defined behavior; this also ends up with the
code slightly simpler.

Defer the "operand size missing" error until we know all the other
operands have the correct type. Otherwise we'll end up with false
positives, which result in noise entered into the xsizeflags array,
thus causing fuzzy matching to fail.
It's possible we should defer it even further.

This allows automatic fuzzy matching of operand sizes. If an operand
size is not specified, but there is exactly one possible size for the
instruction, select that instruction size. This requires a second
pass through the instruction patterns, and so is slightly slower, but
should be a lot easier to get right than the S- flags, and works even
when there is more than one instruction.
The new SX (Size eXact) flag can be used to prevent fuzzy matching
completely.

Move the instruction-matching loop into a common function. This gives
us a single point to adjust the instruction-selection algorithm.

We only ever invoked the preprocessor with fixed values for efunc and
evalfunc, so call nasm_error() and evaluate() directly.

We never invoked the parser with anything but the default definitions
for evaluate and efunc. Unlike the backend, though, we sometimes
invoke parse_line() with redefine_label() instead of define_label().

We never set ofmt and errfunc to anything but the global values.
Dropping them from the label definition function command line
simplifies the code.

Remove a bunch of function pointers in the output stage; they are
never changed and don't add any value. Also make "ofile" a global
variable and let the backend use it directly.
All we ever did with these variables were stashing it in locals and
using them as-is anyway for no benefit.
Also change the global error function, nasm_error() into a true
function which invokes a function pointer internally. That lets us
use direct calls to it.

Before checkin aeb0e0e9f1 we would only
invoke ofmt->symdef() for a common variable during pass 2 if that
variable had "special" in the declaration. That checkin
unintentionally changed that behavior.
That doesn't mean that the pre-existing behavior is right, but this
should at least fix the resulting regressions. This really warrants
more investigation.
