Conor McCarthy : vkd3d-shader/spirv: Shift the private variable destination mask instead of the source mask.

[Alexandre Julliard]

Module: vkd3d
Branch: master
Commit: dbd7e18364cededf51ec2bcc8fdca8b2b06f3371
URL:    https://source.winehq.org/git/vkd3d.git/?a=commit;h=dbd7e18364cededf51ec2bcc...

vkd3d-shader/spirv: Shift the private variable destination mask instead of the source mask.

Otherwise if the input is located above position 0 in the private array
it will be swizzled incorrectly, e.g. a.yz instead of a.xy in
test_domain_shader_inputs().

Based on a vkd3d-proton patch by Hans-Kristian Arntzen.
