With shaders using a lot of inputs/outputs, like this (from Gtk+) :
layout(location = 0) in vec2 inPos;
layout(location = 1) in float inGradientPos;
layout(location = 2) in flat int inRepeating;
layout(location = 3) in flat int inStopCount;
layout(location = 4) in flat vec4 inClipBounds;
layout(location = 5) in flat vec4 inClipWidths;
layout(location = 6) in flat ColorStop inStops[8];
layout(location = 0) out vec4 outColor;
we're missing the programming of the input_slots_valid field leading
to an assert further down the backend code.
Note that we need the shader to be translated from spirv before we can
get the number of inputs/outputs so we set this in a post function and
leave the field at 0 for hashing.
