CELL: fix stencil twiddling, stencil invert
Many stencil tests were failing because of a failure to read the stencil buffer, due to "twiddling" (or "untwiddling") "an unsupported texture format". This is fixed for the case of a stencil/Z S824Z format (which twiddles just like the 32-bit color formats). tests/stencilwrap.c was failing on the GL_INVERT test, because the emitted code for "spe_xori" turned out not to be an actual "xori" instruction, but rather a "stqd" instruction, because of a typo in the rtasm code. This is now fixed, and tests/stencil_wrap now works.
