expr: data_reg: use 'reg' instead of 'data_reg'

data_reg is unnecessarily long name and it always has to be
wrapped by another data node. This will allow us to represent
data not only as registers if needed.

Get rid of 'cmpdata' and 'immediatedata' too and use 'data'
instead to wrap 'reg' so these are consistent with the bitwise
expression. No reason for such specific tag per expression.
