Fix parsing of return statements.

Previously, we would not detect brace initializer lists in return
statements, thus:
 return (a)(b) { 1, 2, 3 };
would put the semicolon onto the next line.

Now correctly formats:

Fix bug discovered by valgrind.

When trying to merge lines, we should not touch lines that are invalid,
as we don't know how long they might be.

Fixes indent in linkage specification blocks.

We now indent:
extern "C" {
int a;
}

without additional indent inside the extern "C" block.

Fix parsing of templated declarations.

Before: template <template <typename T>, typename P > class X;
After:  template <template <typename T>, typename P> class X;

More importantly, the token annotations for the second ">" are now computed
correctly.

Introduce a fast path for the ASTReader's name lookup within a
DeclContext. When the DeclContext is of a kind that can only be
defined once and never updated, we limit the search to the module file
that conatins the lookup table. Provides a 15% speedup in one
modules-heavy source file.

When deserializing a declaration, don't look for redeclarations if its
kind indicates that it can never be redeclared. Good for a 1% speedup,
and redeclaration searching drops off the profile.

Fixes formatting of empty blocks.

We now only put empty blocks into a single line, if all of:
- all tokens of the structural element fit into a single line
- we're not in a control flow statement

Note that we usually don't put record definitions into a single line, as
there's usually at least one more token (the semicolon) after the
closing brace. This doesn't hold when we are in a context where there is
no semicolon, like "enum E {}".

There were some missing tests around joining lines around the corner
cases of the allowed number of columns, so this patch adds some.

When loading an identifier from an AST file solely for the purpose of
forming the identifier, e.g., as part of a selector or a declaration
name, don't actually deserialize any information about the
identifier. Instead, simply mark it "out-of-date" and we'll load the
the information on demand. 2% speedup on the modules testcase I'm
looking at; should also help PCH.

ReadSourceManagerBlock is skipping over records that can contain Blobs.  Not passing
in a StringRef to bind to them forces them to be unpacked into the Record as individual
bytes.  This is wasteful, but not likely to be measurable in this instance.

Replace some unnecessary O(N^2) lookups for properties with
DeclContext lookups. The performance win is negligible in my tests,
but it's the Right Thing To Do (TM).
