Fix wrong-code bug when a const automatic variable of struct type has both a
...
mutable member and a constant initializer. We'd previously promoted such
variables to global constants, resulting in nasal demons if the mutable member
was modified.
This is only a temporary fix. The subtle interplay between isConstantInitializer
and CGExprConstant is very bug-prone; there are some other issues in this area
which I will be addressing in subsequent, more major reworking of this code.

Add bigger method type encodings to protocol objects. <rdar://problem/10492418>
...
The new metadata are method @encode strings with additional data.
1. Each Objective-C object is marked with its class name and protocol names.
The same is done for property @encode already.
2. Each block object is marked with its function prototype's @encoding. For
example, a method parameter that is a block object that itself returns void
and takes an int would look like:
@?<v@?i>
These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.
