2. Generate the actual ir_call (assuming we found the callee).

Trying to do both in one function is just too unwieldy.  Time to split.

This could be done via the existing mechanisms:

However, this requires walking the list of function signatures twice,

This could be rather expensive.

This is a band-aid for these two problems:
- The R600 and EG control-flow instructions appear in switch statements
  next to each other, causing conflicts when adding new instructions.
- The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29
  to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST
  is 22:29.

To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23,
or 26 (directly in the definitions), such that it can be just or'd when making
bytecode without any shifting. All switch statements have been divided into
two, one for R600 and the other for EG.

Of course, there is a better way to do this, but that is left for future
work.
