Chandler Carruth b024aa021d Make the unreachable probability much much heavier. The previous 
probability wouldn't be considered "hot" in some weird loop structures
or other compounding probability patterns. This makes it much harder to
confuse, but isn't really a principled fix. I'd actually like it if we
could model a zero probability, as it would make this much easier to
reason about. Suggestions for how to do this better are welcome.

Douglas Gregor 022857e03d When deserializing an Objective-C class, check whether we have another 
declaration of that same class that either came from some other module
or occurred in the translation unit loading the module. In this case,
we need to merge the two redeclaration chains immediately so that all
such declarations have the same canonical declaration in the resulting
AST (even though they don't in the module files we've imported).

Focusing on Objective-C classes until I'm happy with the design, then
I'll both (1) extend this notion to other kinds of declarations, and
(2) optimize away this extra checking when we're not dealing with
modules. For now, doing this checking for PCH files/preambles gives us
better testing coverage.

Jim Grosbach 1152cc0cad ARM asm parser should be more lenient w/ .thumb_func directive. 
Rather than require the symbol to be explicitly an argument of the directive,
allow it to look ahead and grab the symbol from the next non-whitespace
line.

Sean Callanan 20bb3aa53a The "desired result type" code in the expression 
parser has hitherto been an implementation waiting
for a use.  I have now tied the '-o' option for
the expression command -- which indicates that the
result is an Objective-C object and needs to be
printed -- to the ExpressionParser, which
communicates the desired type to Clang.

Now, if the result of an expression is determined
by an Objective-C method call for which there is
no type information, that result is implicitly
cast to id if and only if the -o option is passed
to the expression command.  (Otherwise if there
is no explicit cast Clang will issue an error.
This behavior is identical to what happened before
r146756.)

Also added a testcase for -o enabled and disabled.
