This combines the C and perfect hash tables into a single source file,
and allows for easier future changes to the source-level structures.
The Python-built files are included in the distribution so that Python
is not added as a dependency.
The generated code has been verified equal against the old tables,
excepting a number of bugfixes.
Most of the bugs fixed are in the CPU field, plus a few GAS suffix fixes.

* modules.vcproj: Add x86cpu.c, x86regtmod.c, and lc3b arch files to fix build.
* x85geninsn.c: Clean up a couple of unused variables.
* genperf.c: Use sprintf instead of snprintf; convert filename backslashes to slashes.

Use the GNU gperf file format, but continue to use our custom minimal
perfect hash generator.

documentation update:
- LZCNT
- POPCNT
- EXTRQ
- INSERTQ
- MOVNTSD
- MOVNTSS
This required some new tricks in the x86 code, as EXTRQ and INSERTQ have
two imm8 parameters (the first one of which goes into the EA field), and
INSERTQ has a *4* parameter version (xmm1, xmm2, imm8, imm8). Instead of
globally making the structures 4 wide, we just special-case INSERTQ.

customize on the arch side of things. Instead of passing around an
arch_data[4] for instructions, now the arch can extend the structure itself
to add additional information in any format it likes.

Two forms are legal ({} are replaceables):
SECTION {segname} {sectname}
SECTION {sectname} segname={segname}
Also,
SECTION {sectname}
where sectname is unrecognized is also legal, defaults segname to __TEXT,
and generates a warning.

string parameters. Value/parameters would now be better called name/values,
but avoid changing the name for now.

and the parser generates EQUs directly for labels in absolute sections.
Fixes#106 and #103.

rax/eax/ax operand. This operand actually selects the address size, so
make it a memory operand instead of a register operand (GAS follows this
approach as well). Enable SVM instructions in non-64-bit mode as well.
Now the following opcodes work as intended:
invlpga [rax/eax/ax], ecx
skinit [eax]
vmload/vmrun/vmsave [rax/eax/ax]

Fix bug relating to recognizing crc32 rax, bh as an error: the opersize=64
changing into REX prefix was happening too late to be caught as an error.
Move this logic from tobytes()/len() functions into finalize(), with proper
prefix handling.

been using a mix of tabs and 4 spaces to indent; this looks horrible if
tab size is ever not 8. While I debated converting to tab-only indentation
that would have been a far higher impact to the source.

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.
