vkd3d-shader/hlsl: Flatten conditional branches containing stores.

For an if block

    if (cond)
    {
        <then_block>
    }
    else
    {
        <else_block>
    }

We flatten it by first replacing any store instruction `v[[k]] = x`
in the then_block with the following:

    1: load(v[[k]])
    2: cond ? x : @1
    3: v[[k]] = @2

Similarly, we replace any store instruction `v[[k]] = x` in the
else_block with the following:

    1: load(v[[k]])
    2: cond ? @1 : x
    3: v[[k]] = @2

Then we can concatenate <then_block> and <else_block> together and
get rid of the if block.

vkd3d-shader/hlsl: Flatten conditional blocks containing discard_nz instructions.

For any `discard_nz c` instruction in a conditional block, we replace c with
    (cond && c)     in a then block,
and
    (!cond && c)    in an else block.

vkd3d-shader/hlsl: Flatten conditional blocks containing discard_neg instructions.

For any `discard_neg c` instruction in a conditional block, we replace c with
    cond ? c : 0    in a then block,
and
    cond ? 0 : c    in an else block.
