The LOOP/ENDLOOP pair is renamed to BGNFOR/ENDFOR as its behaviour
is similar to a C language for-loop.
The BGNLOOP2/ENDLOOP2 pair is renamed to BGNLOOP/ENDLOOP as now
there is no name collision.

Various opcodes which can be implemented trivially with other TGSI opcodes,
such as matrix multiplication and negation. These were not used by any
state tracker or implemented by any of the drivers.

This is a source of ongoing confusion. TGSI has multiple names for
opcodes where the same semantics originate in multiple shader APIs.
For instance, TGSI includes both Mesa/GLSL and DX/SM30 names for
opcodes with the same semantics, but aliases those names to the same
underlying opcode number.
This makes it very difficult to visually inspect two sets of opcodes
(eg in state tracker & driver) and check if they implement the same
functionality.
This patch arbitarily rips out the versions of the opcodes not currently
favoured by the mesa state tracker and leaves us with a single name
for each distinct operation.

The debug functions depend on several util function for os abstractions, and
these depend on debug functions, so a seperate module is not possible.

KIL takes 1 src register. KILP uses no registers (uses cond codes).
