25f6dfd108 Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine.

083a8eb063 Generate the dispatch code for a 'thumb' function. This is very similar to the 
others. They take the call site value. Determine if it's a proper value. And
then jumps to the correct call site via a jump table.

4df1557f40 Don't require C bindings opcode numbers to be kept in sync. 
They are not in sync now, for example Bitcast would show up as LLVMCall.
So instead introduce 2 functions that map to and from the opcodes in the C
bindings.

d9c1fa5205 Remove the TRI::getSubRegisterRegClass() hook. 
This restores my karma after I added TRI::getSubClassWithSubReg().

Register constraints are applied 'backwards'.  Starting from the
register class required by an instruction operand, the correct question
is: 'How can I constrain the super-register register class so all its
sub-registers satisfy the instruction constraint?' The
getMatchingSuperRegClass() hook answers that.

We never need to go 'forwards': Starting from a super-register register
class, what register class are the sub-registers in?  The
getSubRegisterRegClass() hook did that.

way.

6da674cda1 Parser Multidef Support 
Add parser support to recognize multidefs.  No processing on the
multidef is done at this point.  The grammar is:

MultiDef = MULTIDEF ObjectName < Value, Declaration, Value > ObjectBody

The first Value must be resolveable to a list and the second Value
must be resolveable to an integer.  The Declaration is a temporary
value used as an iterator to refer to list items during processing.
It may be passed into the ObjectBody where it will be substituted with
the list value used to instantiate each def.
