wined3d: More flow control instructions
- Implement if, else, endif, rep, endrep, break
- Implement ifc, breakc, using undocumented comparison bits in the instruction token
- Fix bug in main loop processing of codes with no dst token
- Fix bug in GLSL output modifier processing of codes with no dst token
- Fix bug in loop implementation (src1 contains the integer data, src0 is aL)
- Add versioning for all the instructions above, and remove
GLSL_REQUIRED thing, which is useless and should be removed from all
opcodes in general.
