awakening noop

[Stefan Reinauer]

Haven't seen these in a while, but they are back with the latest romcc
release:

apic.h:100.1: auto.c:123.19: auto.c:197.30: 0x735c00 noop Internal compiler warning: awakening noop?
apic.h:100.1: auto.c:129.19: auto.c:197.30: 0x736b90 noop Internal compiler warning: awakening noop?

Don't think they're saying anything else but that a dead subtree was
detected in the code?
