Update prebuilt Clang to r365631c1 from Android.
The version we had was segfaulting.

+/// \class StructuredData StructuredData.h "lldb/Utility/StructuredData.h"
+/// A class which can hold structured data
+///
+/// The StructuredData class is designed to hold the data from a JSON or plist
+/// style file -- a serialized data structure with dictionaries (maps,
+/// hashes), arrays, and concrete values like integers, floating point
+/// numbers, strings, booleans.
+///
+/// StructuredData does not presuppose any knowledge of the schema for the
+/// data it is holding; it can parse JSON data, for instance, and other parts
+/// of lldb can iterate through the parsed data set to find keys and values
+/// that may be present.
