[scan-build] fix logic error warnings emitted on llvm code base

Changes since last revision:

- lib/CodeGen/ScheduleDAGInstrs.cpp: remove assert and nullptr check on MachineInstr pointer to suppress analyzer warning: dereferencing MI pointer will induce a crash if it is null anyway,

- lib/Target/ARM/ARMFrameLowering.cpp: remove assert and nullptr check on RegScavenger pointer since ARMBaseRegisterInfo::requiresRegisterScavenging() always returns true,

- lib/Target/ARM/Thumb2SizeReduction.cpp: move assert closer to corresponding code block.
