Adjust LSHIFT_EXPR handling of multiple_of_p

This removes the odd check of size_type_node when handling left-shifts
as multiplications of 1 << N and instead uses the type as specified.
It also moves left-shift handling next to multiplications where it
semantically belongs.

* fold-const.cc (multiple_of_p): Re-write and move LSHIFT_EXPR
handling.
