if *none* of the successors of the call expression is the exit block.
This matters when a call of bool type is the condition of (say) a while
loop in a function with no statements after the loop.  This *can* happen
in C, but it's much more common in C++ because of overloaded operators.

Suppresses some substantial number of spurious -Wmissing-noreturn warnings.

specializations, which keeps track of the order in which they were
originally declared. We use this number so that we can always walk the
list of partial specializations in a predictable order during matching
or template instantiation. This also fixes a failure in Boost.Proto,
where SourceManager::isBeforeInTranslationUnit was behaving
poorly in inconsistent ways.

InjectedClassNameType's Decl to point at the definition. It's a little
messy, but we do the same thing with classes and their record types,
since much of Clang expects that the TagDecl* one gets out of a type

This does not hurt performance much. The analysis time for sqlite3.c:

before:
real    17m52.440s
user    17m49.460s

after:
real    18m0.500s
user    17m56.900s
sys    0m2.330s

DisplayProgress option is broken now. -inine-call action is removed. It
will be reenabled in another form, perhaps as an indenpendant option.

address of an overloaded function (or function template), perform that
resolution prior to determining the implicit conversion
sequence. This resolution is not part of the implicit conversion
sequence itself.

Previously, we would always consider this resolution to be a
function pointer decay, which was a lie: there might be an explicit &
in the expression, in which case decay should not occur. This caused
the CodeGen assertion in PR6973 (where we created a 
pointer to a pointer to a function when we should have had a pointer
to a function), but it's likely that there are corner cases of
overload resolution where this would have failed.

Cleaned up the code involved in determining the type that will
produced afer resolving the overloaded function reference, and added
an assertion to make sure the result is correct. Fixes PR6973.
