emit_ios handles all the shader types so that it is difficult to
follow what is emitted for which shader type. Start refactoring by
moving the common initialization into a separate function.

We already track samplers, images and ssbos using bitmasks, so this is a

Also, this is going to enable some other nifty optimizations later on.

TGSI_OPCODE_BFI and TGSI_OPCODE_ATOMCAS takes four source arguments,
so we actually need to support up to four members here. Luckily, the
storage passed to this function was large enough, so no actual harm
happened, just a small semantic issue when reading the source code.

TGSI defines TGSI_SEMANTIC_SAMPLEPOS as a 4-component vector with
Z and W set to 0. However, if we ever try to reach thez and w
compoents, we run into trouble because this is implemented as a
swizzle on gl_SamplePosition instead. And gl_SamplePosition only
has x and y.
It seems that recent versions of mesa does just this, causing
shader-compilation errors during dEQP tests.
