assembler: Make explicit that labels are part of the instructions list

Browse Source 
The output of the parsing is a list of struct brw_program_instruction.
These instructions can be either GEN instructions aka struct
brw_instruction or labels. To make this more explicit we now have a type
to test to determine which instruction we are dealing with.

This will also allow to to pull the relocation bits into struct
brw_program_instruction instead of having them in the structure
representing the opcodes.
