[Nouveau] [PATCH mesa v2 1/3] nouveau: codegen: Disable more old resource handling code

[Hans de Goede]

Commit c3083c7082 ("nv50/ir: add support for BUFFER accesses") disabled /
commented out some of the old resource handling code, but not all of it.

Effectively all of it is dead already, if we ever enter the old code
paths in handeLOAD / handleSTORE / handleATOM we will get an exception
due to trying to access the now always zero-sized resources vector.

Disable all the dead code.

Changes in v2:
-Split out assert() on getFile() != BUFFER/MEMORY into a separate patch
-Split out removal of TGSI_RESOURCE_* defines into a separate patch
