[SelectionDAG] Not issue TRAP node if naked function (#132147)
In [1], Nikita Popov suggested that during lowering 'unreachable' insn
should not generate extra code for naked functions, and this applies to
all architectures. Note that for naked functions, 'unreachable' insn is
necessary in IR since the basic block needs a terminator to end.
This patch checked whether a function is naked function or not. If it is
a naked function, 'unreachable' insn will not generate ISD::TRAP.
