(and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in
an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.
Fixes <rdar://problem/8380046>.

aliases. Previously, the location of the alias was at the "namespace"
keyword. Now, it's on the identifier being declared (as is the custom
for Clang), and we keep a separate source location for the "namespace"
keyword.
Also, added a getSourceRange() member function to NamespaceAliasDecl
to correctly compute the source range.
Finally, removed a bunch of setters from NamespaceAliasDecl and gave
ASTReaderDecl friendship so that it could set the corresponding fields
directly.

*Huge* improvement over the amount of deserializing that we do for C++ lookup.
e.g, if he have the Carbon header precompiled and include it on a file containing this:
int x;
these are the before/after stats:
BEFORE:
*** AST File Statistics:
578 stat cache hits
4 stat cache misses
548/30654 source location entries read (1.787695%)
15907/16501 types read (96.400223%)
53525/59955 declarations read (89.275291%)
33993/43525 identifiers read (78.099945%)
41516/51891 statements read (80.006165%)
77/5317 macros read (1.448185%)
0/6335 lexical declcontexts read (0.000000%)
1/5424 visible declcontexts read (0.018437%)
AFTER using the on-disk table:
*** AST File Statistics:
578 stat cache hits
4 stat cache misses
548/30654 source location entries read (1.787695%)
10/16501 types read (0.060602%)
9/59955 declarations read (0.015011%)
161/43525 identifiers read (0.369902%)
20/51891 statements read (0.038542%)
6/5317 macros read (0.112846%)
0/6335 lexical declcontexts read (0.000000%)
2/5424 visible declcontexts read (0.036873%)
There's only one issue affecting mostly the precompiled preambles which I will address soon.
