The implementations here just clone i2b32 and i2b1. This means that
b2b32 doesn't technically generate true NIR 0/-1 booleans but it should
be fine as it's only ever generated for shared variable writes which
will always be consumed by something which will then run it through an
i2b again.

We know that in this case, the LS and HS invocations are working

Clear the workgroup size for all supported shader stages.
Also, unify the workgroup size calculation accross various places.
As a result, insert_waitcnt can use the proper workgroup size
which means that some waits can be dropped from tessellation
shaders. Also, in cases where the previous calculation was wrong,
we now insert s_barrier instructions.

When TCS has an equal number of input and output, it means that the
number of VS and TCS invocations (LS and HS) are the same; and that
the HS invocations operate on the same vertices as the LS.
When this is the case, this commit removes the else-if between
the merged VS and TCS halves, making it possible to schedule
and optimize the code accross the two halves.

64-bit VGPR constant copies can happen because of 64-bit constant copy
propagation. Since this optimization is beneficial and more annoying to
deal with in the optimizer, I've implemented 64-bit VGPR constant copies
in handle_operands().
This also sets copy_operation::size correctly for 64-bit constant copies.
