Craig Topper e33ed7d667 [X86] Remove DATA32_PREFIX. Hack the printing for DATA16_PREFIX to print 'data32' in 16-bit mode. Hack the asm parser to convert 'data32' to 'data16' in 16-bit mode. 
Improve the error messages to match GNU assembler.

This also allows us to remove the hack from the disassembler table building.

Craig Topper 097b47a0fc [X86] Add a new disassembler opcode map for 3DNow. Stop treating 3DNow as an attribute. 
This reduces the size of llvm-mc by at least 150k since we no longer have to multiply the attribute across 7 tables.

Rafael Auler de9ad4ba84 [X86][3DNOW] Teach decoder about AMD 3DNow! instrs 
Summary:
This patch makes the decoder understand old AMD 3DNow!
instructions that have never been properly supported in the X86
disassembler, despite being supported in other subsystems. Hopefully
this should make the X86 decoder more complete with respect to binaries
containing legacy code.

Marina Yatsina 197db00e3e [X86] Fix for bugzilla 31576 - add support for "data32" instruction prefix 
This patch fixes bugzilla 31576 (https://llvm.org/bugs/show_bug.cgi?id=31576).

"data32" instruction prefix was not defined in the llvm.
An exception had to be added to the X86 tablegen and AsmPrinter because both "data16" and "data32" are encoded to 0x66 (but in different modes).

Craig Topper 055845f5cb [X86] Make the instructions that use AdSize16/32/64 co-exist together without using mode predicates. 
This is necessary to allow the disassembler to be able to handle AdSize32 instructions in 64-bit mode when address size prefix is used.

Eventually we should probably also support 'addr32' and 'addr16' in the assembler to override the address size on some of these instructions. But for now we'll just use special operand types that will lookup the current mode size to select the right instruction.

Craig Topper b86338f7b2 [X86] Remove the single AdSize indicator and replace it with separate AdSize16/32/64 flags. 
This removes a hardcoded list of instructions in the CodeEmitter. Eventually I intend to remove the predicates on the affected instructions since in any given mode two of them are valid if we supported addr32/addr16 prefixes in the assembler.

David Woodhouse caaa2850c0 [x86] Fix disassembly of MOV16ao16 et al. 
The addition of IC_OPSIZE_ADSIZE in r198759 wasn't quite complete. It
also turns out to have been unnecessary. The disassembler handles the
AdSize prefix for itself, and doesn't care about the difference between
(e.g.) MOV8ao8 and MOB8ao8_16 definitions. So just let them coexist and
don't worry about it.

David Woodhouse 32da3c8f3b [x86] Fix MOV8ao8 et al for 16-bit mode, fix up disassembler to understand 
It seems there is no separate instruction class for having AdSize *and*

these instructions. So add that to the disassembler.

Hm, perhaps we do need an AdSize16 bit after all?
