[Hexagon] Lower funnel shifts for HVX
HVX v62+ has bidirectional shifts, which do not mask the shift amount to
the bit width. Instead, the shift amount is sign-extended from the log(BW)
bit value, and a negative value causes a shift in the other direction.
For the shift amount being -log(BW), this reversed shift will shift all
bits out, inserting 0s or sign bits depending on the type and direction.
