Formatter: Put spaces in ObjC method decls in the right place for Google style.

Objective-C method declarations look like this:

- (returntype)name:(type)argname anothername:(type)arg2name;

In google style, there's no space after the leading '-' but one after
"(returntype)" instead (but none after the argument types), see
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Method_Declarations_and_Definitions

Not inserting the space after '-' is easy, but to insert the space after the
return type, the formatter needs to know that a closing parenthesis ends the
return type. To do this, I tweaked the code in parse() to check for this, which
in turn required moving detection of TT_ObjCMethodSpecifier from annotate() to
parse(), because parse() runs before annotate().

(To keep things interesting, the return type is optional, but it's almost
always there in practice.)

c++ IRGen. In trivial cases that object is going into static
storage and thus is implicitly zero-initialized, no need to
do C++11 memory model. This patch unconditionally detects
such condition and zeroinitializer's the variable.
Patch has been commented on and OKed by Doug off-line.

[analyzer] Allow IvarInvalidation checker to suppress warnings via
assertions.

To ensure that custom assertions/conditional would also be supported,
just check if the ivar that needs to be invalidated or set to nil is
compared against 0.

Unfortunately, this will not work for code containing 'assert(IvarName)'

Truth in advertising: LocallyScopedExternalDecls actually only contains
external declarations with C language linkage.
