Fixed handling of macros at the end of vertex shaders.
Handled NOP and PHASE instructions.
Fixed versions of several instructions.
Improved pixel shader dump traces.
Fixed write mask.
Fixed X2 and -X2 source modifiers and implements DZ and DW ones.
Implemented texcrd, texld, texm3x3pad, texm3x3tex, texm3x3spec and
texm3x3vspec instructions (and partially texbem).
Added cnd, cmp and lrp instructions.
Rewrite of the "autoparam" code so we can add more complicated
instructions (only cnd and cmp as well as simple instructions use that
code at the moment).
