accf94ea24 Better handling of 32-bit imms in 64-bit moves 
A much better way to handle the 32-bit immediates in 64-bit moves.
Add a test file.

65e823978b insns.dat: add "MOV reg64,imm32" as a special rule 
Add "MOV reg64,imm32" as a special rule, to handle the case of
"mov rax,dword <foo>", where <foo> is sign-extended; this is a 7-byte
form, as opposed to "mov eax,<foo>" (5 bytes) and "mov rax,<foo>" (10
bytes).

At some point, the optimizer needs to be able to handle these.

d60059ef41 Display fully qualified local label in "not defined" message 
Add new function "local_scope" to label subsystem to
return the previous non-local label for a given local label,
and invoke this funcion in eval.c to display the fully
qualified name in the "not defined" error message.

27713625c1 outform: make OF_DOS include OF_COFF 
DJGPP uses COFF as the file format.  Since DJGPP is widely used in the
(remaining) DOS world, include OF_COFF in OF_DOS.

88ab419cc6 OpenWatcom: optimize for 686 
Apparently -6 compiles are defined to run on anything 386 or newer,
and just use different instruction timings.

714ad04bb8 Some compilers define __386__ instead of __i386__

defines __386__ rather than __i386__.

338a3b6882 Clear up WRITE macros causing compile failures with Watcom 
The OpenWatcom compiler warns about invalid shifts (correctly, it
appears) due to the non-X86_MEMORY versions of the various WRITE
macros.  Fix.

f6c51f084b Add XSAVE instruction features (CPU feature is bogus, but oh well.) 
Add the XSAVE group of instructions: XSAVE, XRSTOR, XGETBV, XSETBV.
The CPU feature information is bogus, but so is our entire handling of
CPU feature sets for anything but the bare necessities (long jump
emulation, etc.)

2b046cf67f Ignore ERR_PASS1 except for actual warnings 
is_suppressed_warning() should never return true unless we're actually
dealing with a warning.  There is a handful of cases where we pass
ERR_PASS1 down together with errors, but that's mostly because it fits
into an overall pattern.  Thus, ignore it.

free(); that way we can find out what the last thing was if free()
