All samplers indexes were zero.

Previously, the shader linker combined the uniforms used by the vertex and
fragment shaders into a combined set of uniforms. This made the implementation
of glUniform*() simple, but was rather inefficient otherwise. Now each shader
gets its own set of uniforms (no more modelview matrix showing up in the
fragment shader uniforms, for example).

Also, remove obsolete matrix codegen code.

substitution.
We had been taking a short-cut w/ asm inlines by just using parameters in order
rather than doing full formal parameter -> actual argument substitution like
ordinary inlined function calls. This worked in all cases but one: mix() in
which the parameters were used in a different order.
This fixes bug 10821.

Also, found/fixed a code generation regression: the emit_swizzle() function
was always returning NULL. This caused emit_move() to miss its chance at peephole
optimization.

IR_LOOP now has two children: the body code, and the tail code.
Tail code is the "i++" part of a for-loop, or the expression at the end
of a "do {} while(expr);" loop.
"continue" translates into: "execute tail code; CONT;"
Also, the test for infinite do/while loops was incorrect.
