Support for Win32 safeseh (BR 195417)
This is basically not a bug report, but a feature request.
It's desired to be able to link .obj modules compiled with 'nasm -f
win32' with Microsoft 'link /safeseh'. As well as to register symbols
(commonly subroutine's entry points or even external symbols) as "safe
handlers." In order to achieve this, several points are required.
First of all, object module has to have absolute symbol named @feat.00
with value of 1. This can actually be achived by adding 'absolute 1'
and '@feat.00:' to source code, but it's desirable that it's
autogenerated for win32 modules.
Handler registration is essentially symbol's *index* in current
module's symbol table in .sxdata, segment with 0x200 segment flags, an
"info" segment. It's also essential that symbol has type 0x20 (see
below). All this is depicted in following framgents of 'objdump -xD'
output:
Sections:
Idx Name Size VMA LMA File off Algn
0 .sxdata
00000004 00000000 00000000 0000003c 2**2
CONTENTS, READONLY, DEBUGGING

...
[ 5](sec -1)(fl 0x00)(ty 0)(scl 3) (nx 0) 0x00000001 @feat.00

0: 06 00 00 00
Note [6] and (ty 20) in _handle line in SYMBOL TABLE. "06 00 00 00" in
.sxdata is little-endian 6, _handler's index. This is what makes up
"registration." It's impossible to achieve this with current nasm
facilities and it's probably appropriate to introduce a directive for
it, 'safeseh _handler' is probably most natural choice.

First cut at AVX machinery.
First cut at AVX machinery support. The only instruction implemented
is VPERMIL2PS, and it's probably buggy. I'm checking this in with the
hope that other people can start helping out with (a) testing this,
and (b) adding instructions.
NDISASM support is not there yet.

Initial support for YMM (AVX) registers
Add support for ymm0..15 registers, and the "ymmreg" qualifier.
No support yet for "yword" or "dy".

Avoid long line warning when generating nasm docs

Avoid some warnings in rdoff/rdf2bin.c
I received some warnings when running make on the head revision of
nasm from git:
----
rdf2bin.c: In function 'main':
rdf2bin.c:122: warning: comparison between signed and unsigned
rdf2bin.c:123: warning: comparison between signed and unsigned
rdf2bin.c:124: warning: comparison between signed and unsigned
----
I think these warnings are innocuous and should be safely avoidable
with simple casts (please see attached patch).
* rdoff/rdf2bin.c
(main): cast to size_t for comparison with fwrite return value

Temporaries in macros need a unique prefix; WSAA*() macros to header
When using temporaries in macros, given them a unique prefix to avoid
namespace collisions when using one macro inside another.
Move the WSAA*() macros from outelf32/outelf64 to a separate header
file.

Restore critical expression checking when optimizer enabled
In the prior code, enabling optimization effectively diabled
critical expression checking, because the optimization passes
took place before checking was enabled.
