If this == NULL, we'll get a crash which is pretty much the same thing
when it comes to ease of debugging. This fixes a giant pile of warnings
with GCC 12 of the form:
../src/compiler/glsl/ir.h: In member function ‘ir_dereference* ir_instruction::as_dereference()’:
../src/util/macros.h:149:30: warning: ‘nonnull’ argument ‘this’ compared to NULL [-Wnonnull-compare]
149 | #define assume(expr) ((expr) ? ((void) 0) \

../src/compiler/glsl/ir.h:160:4: note: in expansion of macro ‘AS_BASE’
