[MachineOutliner][X86] Use TAILJMPd64 instead of JMP_1 for TailCall construction
The machine verifier asserts with:
Assertion failed: (isMBB() && "Wrong MachineOperand accessor"), function getMBB, file ../include/llvm/CodeGen/MachineOperand.h, line 542.
It calls analyzeBranch which tries to call getMBB if the opcode is
JMP_1, but in this case we do:
JMP_1 @OUTLINED_FUNCTION
I believe we have to use TAILJMPd64 instead of JMP_1 since JMP_1 is used
with brtarget8.
