32cd4c2a62 Correctly identify SBYTE in the optimizer 
Correctly identify SBYTE in the optimizer, *HOWEVER*, this change will
cause nuisance warnings to be issued; that will have to be fixed.

5a7976c925 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.

accf94ea24 Better handling of 32-bit imms in 64-bit moves

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.

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

appears) due to the non-X86_MEMORY versions of the various WRITE

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()
crashes.
