New Revision: 43474

URL: http://llvm.org/viewvc/llvm-project?rev=43474&view=rev
Log:
Added support for StmtIterators to iterate over the size expressions
of VariableArrayTypes that appear in TypedefDecls.

for example:

  typedef int T[x][x];

the StmtIterator will iterate over "x" and "x" as subexpressions of
the DeclStmt for T.
