CELL: fixing stencil bugs
These are the defects found and fixed so far. Several more have been observed; I'm working on them. - Fixed an error in spe_load_uint() that caused incorrect values to be loaded if the given unsigned value had the low 18 bits as 0, and that caused inefficient code to be emitted if the given value had the high 14 bits as 0. - Fixed a problem in stencil code generation where optional registers weren't tracked correctly. - Fixed a problem that the stencil function NEVER was acting as ALWAYS. - Fixed several problems that could occur if stenciling were enabled but depth was disabled. - Fixed a problem with two-sided stencil writemask handling that could cause a stencil writemask to not be applied. - Fixed several state permutations that were incorrectly flagged as not requiring stencil values to be calculated.
