Fix VarListElementInit::resolveListElementReference to return a
partially resolved VarListElementInint in the case where full
resolution is not possible.  This allows TableGen to make forward
progress resolving certain complex list expressions.

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.

Fix assembling of xchg %eax, %eax to not use the NOP encoding of 0x90. This was done by creating a new register group that excludes AX registers. Fixes PR10345. Also added aliases for flipping the order of the operands of xchg <reg>, %eax.

Also use a frame load instead of store for the LD instruction.

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.

merging an lsl #2 that has multiple uses on A9. This shift is free, so there is
no problem merging it in multiple places. Other unprofitable shifts will not be
merged.

Fix the argument passed in the multidef example.

For consistency, prefix multiclass template arg names with the
multiclass name followed by "::" to avoid name clashes among
multiclass arguments and other entities in the multiclass.

Add Emacs font-lock keyword support for multidefs.

Provide documentation for multidefs, explaining in detail how they
work.

Update the MultiPat.td test to create some defs via multidefs.

Add a simple test for multidefs.
