We don't use it and it was removed in gfx9, and the encoding
bit repurposed.
Additionally actually using it requires changing the output register
class, which wasn't done anyway.

As we introduced target triple environment amdgiz and amdgizcl, the address
space values are no longer enums. We have to decide the value by target triple.
The basic idea is to use struct AMDGPUAS to represent address space values.
For address space values which are not depend on target triple, use static
const members, so that they don't occupy extra memory space and is equivalent
to a compile time constant.
Since the struct is lightweight and cheap, it can be created on the fly at
the point of usage. Or it can be added as member to a pass and created at
the beginning of the run* function.

Use vaddr/vdst for the same purposes.
This also fixes a beg in SIInsertWaits for the
operand check. The stored value operand is currently called
data0 in the single offset case, not data.

While trying to add the glc bit to SMEM instructions on VI
with the new refactoring I ran into some kind of shadowing
problem for the glc operand when using the pseudoinstruction
as a multiclass parameter.
Everywhere that currently uses it defines the operand to have the same
name as its type, i.e. glc:$glc which works. For some reason now it
conflicts, and its up evaluating to the wrong thing. For the
real encoding classes,
let Inst{16} = !if(ps.has_glc, glc, ?); was not being evaluated
and still visible in the Inst initializer in the expanded td file.
In other cases I got a a different error about an illegal operand
where this was using { 0 } initializer from the bits<1> glc initializer
instead of evaluating it as false in the if.
For consistency all of the operand types should probably
be captialized to avoid conflicting with the variable names
unless somebody has a better idea of how to fix this.
