Add support for MODE_VECTOR_BOOL
This patch adds a new mode class to represent vectors of booleans.
GET_MODE_BITSIZE (m) / GET_MODE_NUNITS (m) determines the number
of bits that are used to represent each boolean; this can be 1
for a fully-packed representation or greater than 1 for an unpacked
representation. In the latter case, the value of bits other than
the lowest is not significant.
These are used by the SVE port to represent predicates.
