[PATCH] D75661: Remove SequentialType from the type heirarchy.

[Christopher Tetreault via Phabricator via cfe-commits]

ctetreau added a comment.

> I'm concerned though about having getSequentialElementType and getSequentialNumElements apply to different sets of types. That's bound to lead to confusion which causes bugs. Can we have one name for all types that are homogenous sequences of the same element type, and a different name for all types which are *fixed-length* homogenous sequences?

isSequentialType() returns true for VectorType and ArrayType. It should be changed to only return true if the vector type is not scalable, and getSequentialNumElements() should assert isSequentialType() before attempting the casts.

In the future, when my proposed FixedVectorType is added, isSequentialType will return true for ArrayType and FixedVectorType only.
