Add element-type to the Vector TypeLoc types.

Authored by erichkeane on Dec 17 2020, 12:15 PM.



As shown by bug 48540, GCC vector types would cause a crash when the
declaration hada ParenType. This was because the walking of the
declaration would try to expand the 'inner' type, but there was no
ability to get it from the vector type. This patch adds that element
type access to the vector type loc objects.

Can we reuse/unify this with MatrixTypeLoc? And then have MatrixTypeLoc just deal with the row/column operands.

Since these have to be ConcreteTypeLocs, I don't think the matrix type can directly inherit from it, but it can do something very similar.

LGTM, thanks


Oh right, that's a shame, given there already is a MatrixTypeLoc, which essentially does the same thing, but it also carries locations for the row and column operands.
