Bug #5976

Shifted bit vector should be of the same size that was a source one

Description

I have to write coerce explicitly:

wmask<1..0> = coerce(card(2), welem<1..0> >>> R)

rather that simply assign the shift result:
wmask<1..0> = welem<1..0> >>> R

Otherwise there would be an error: can't assign 32-bit value to a 2-bit field!

Generated JAVA for the explicit coerce case

wmask.access().bitField(1, 0).store(DataEngine.coerce(Type.CARD(2), DataEngine.execute(EOperatorID.R_ROTATE,
  DataEngine.coerce(Type.CARD(32), welem.access().bitField(1, 0).load()), R.access().load())));
