nir/spirv: Handle OpBranchConditional

We do control-flow handling as a two-step process.  The first step is to
walk the instructions list and record various information about blocks and
functions.  This is where the acutal nir_function_overload objects get
created.  We also record the start/stop instruction for each block.  Then
a second pass walks over each of the functions and over the blocks in each
function in a way that's NIR-friendly and actually parses the instructions.
