[Hexagon] Skip byval arguments when checking parameter attributes From the point of view of register assignment, byval parameters are ignored: a byval parameter is not going to be assigned to a register, and it will not affect the assignments of subsequent parameters. When matching registers with parameters in the bit tracker, make sure to skip byval parameters before advancing the registers. llvm-svn: 278375
