Set hasSideEffects=0 for TargetOpcode::{CFI_INSTRUCTION,EH_LABEL,GC_LABEL,ANNOTATION_LABEL}
D37065 (committed as rL317674) explicitly set hasSideEffects for all
TargetOpcode::* instructions where it was inferred previously. This is a
follow-up to that patch, setting hasSideEffects=0 for CFI_INSTRUCTION,
EH_LABEL, GC_LABEL and ANNOTATION_LABEL. All LLVM tests pass after this
change.
This patch also modifies MachineInstr::isLabel returns true for a
TargetOpcode::ANNOTATION_LABEL, which ensures that an annotation label won't
be incorrectly considered safe to move.
