fix(mips32r6): jic is not call but jump

Browse source 
See https://s3-eu-west-1.amazonaws.com/downloads-mips/documents/MD00086-2B-MIPS32BIS-AFP-6.06.pdf,
page 205 (page 215 in file).
jic is not like jialc, which set ra by `GPR[31] <- PC + 4`, it's just a jump.
So, if meet jic reg,xxx , identify it as a jump.
If meet jic ra,xxx , identify it as a return.
