and common declare. The latter no longer passes through objfmt at parse time;
instead the objfmt must handle them at output time (objfmt-specific
extensions are parsed & stored by the parser). Directives are now handled
using a list (with function pointers) rather than a single function entry
point.

yasm_dbgfmt, and yasm_arch. This eliminates a lot of redundant keeping
track of this information in the individual object and debug formats and
also simplifies a fair amount of code.
I'm still not happy with how arch gets passed around in output code, but
there may not be much of an alternative there.
While I'm here, clean up some unused variables and functions and re-enable
the warning for unused variables in configure.ac.

in load commands. This caused test miscompares on other platforms and
could conceivably cause yasm to crash by reading beyond proper boundaries
(but this is unlikely). Functionally the output is the same.

While here, fix a few warnings by pushing uintptr_t to a few more register

Note that due to an m4 bug, you need at least m4 1.4.5, and autoconf built
with the newer version of m4, to run autoconf on the source now (this does
not apply if you're just running ./configure from a tarball).

This commit adds the necessary directives and some higher-level macros to
make it easier to generate the .xdata and .pdata sections needed for
structured exception handling on Win64. The overall construction mirrors
MASM very closely, so it should be possible for near-direct translation of
MASM code to Yasm; see for example objfmts/win64/tests/sce3.masm and
objfmts/win64/tests/sce4.asm. This commit does *not* break generating these
yourself (which you may want to do if you're a compiler).
This commit adds special proc macros so the function layout will look like:
proc_frame <procname>
... (frame setup and unwind directives)
end_prologue (or alternatively [endprolog])
...
endproc_frame
The "raw pseudo operations" (.directives) as described in MSDN
(http://msdn2.microsoft.com/en-us/library/ms235231(VS.80).aspx)
have been exactly mirrored in Yasm, as follows:
[pushreg], [setframe], [allocstack], [savereg], [savexmm128], [pushframe],
[endprolog]
Note the [] are required.
Additionally, the following macros have been implemented that MASM provides
in ksamd64.inc, and as documented in MSDN
(http://msdn2.microsoft.com/en-us/library/ms235217(VS.80).aspx):
push_reg, rex_push_reg, push_eflags, rex_push_eflags, alloc_stack,
save_reg, save_xmm128, push_frame, set_frame, end_prologue
I'll next work on getting all of this documented in the user manual.

a lower level.
To reduce code duplication, refactor several of the large if/else structures
into multiple functions with a lookup table.
Add support for registers to be used in directive expressions.
Allow directives to have underscores and numbers (still cannot start with
numbers).
