intel/decoders: limit number of decoded batchbuffers

IGT has a test to hang the GPU that works by having a batch buffer
jump back into itself, trigger an infinite loop on the command stream.
As our implementation of the decoding is "perfectly" mimicking the
hardware, our decoder also "hangs". This change limits the number of
batch buffer we'll decode before we bail to 100.

st/glsl: start spilling out common st glsl conversion code

The NIR and TGSI paths are currently intertwined which makes it
not only hard to follow but also makes it hard to take advantage
of the differences in IR.

The speed-up can be measured in some dolphin uber shaders due to

In the old code, we would generate the exact same instruction for
