[ValueTypes] Add EVT::isFixedLengthVector
Summary:
Related to D75672, this patch adds EVT::isFixedLengthVector to determine
if the underlying vector type is of fixed length.
An assert is introduced in EVT::getVectorNumElements that triggers for
types that aren't fixed length. This is currently guarded by a flag
added D75297 that is off by default and has been renamed to the more
generic ENABLE_STRICT_FIXED_SIZE_VECTORS.
Ideally we want to get rid of getVectorNumElements but a quick grep
shows there are >350 uses in lib/CodeGen and 75 in lib/Target/AArch64
alone. All of these probably aren't EVT::getVectorNumElements (some may
be the MVT equivalent), but there are many places to fixup and having
the assert on by default would make the SVE upstreaming effort
difficult.
