Dale Johannesen 2050968df9 Clear the cached cost when removing a function in
the inliner; prevents nondeterministic behavior
when the same address is reallocated.
Don't build call graph nodes for debug intrinsic calls;
they're useless, and there were typically a lot of them.

Dan Gohman 37061eef5d Add a liveness analysis pass for LLVM IR values. This computes
the set of blocks in which values are used, the set in which
values are live-through, and the set in which values are
killed. For the live-through and killed sets, conservative
approximations are used.

Douglas Gregor 90a1a65194 Introduce a new expression type, UnresolvedDeclRefExpr, that describes
dependent qualified-ids such as

  Fibonacci<N - 1>::value

where N is a template parameter. These references are "unresolved"
because the name is dependent and, therefore, cannot be resolved to a
declaration node (as we would do for a DeclRefExpr or
QualifiedDeclRefExpr). UnresolvedDeclRefExprs instantiate to
DeclRefExprs, QualifiedDeclRefExprs, etc.

Also, be a bit more careful about keeping only a single set of
specializations for a class template, and instantiating from the
definition of that template rather than a previous declaration. In
general, we need a better solution for this for all TagDecls, because
it's too easy to accidentally look at a declaration that isn't the
definition.

We can now process a simple Fibonacci computation described as a
template metaprogram.

Dale Johannesen 52bc2aac8a This pass keeps a map of Instructions to Rank numbers,
and was deleting Instructions without clearing the
corresponding map entry.  This led to nondeterministic
behavior if the same address got allocated to another
Instruction within a short time.

Daniel Dunbar 2da027244d Driver: Claim -arch options when pipelining, and claim arguments that
are forwarded to GCC.
 - The later is unfortunate, as it prevents us from generally warning
   about anything interesting on platforms that use a generic
   toolchain. However, we can't do much better without significantly
   complicating things, and generally we should have proper tool chain
   definitions.

Douglas Gregor 1835391025 Generalize printing of nested-name-specifier sequences for use in both
QualifiedNameType and QualifiedDeclRefExpr. We now keep track of the
exact nested-name-specifier spelling for a QualifiedDeclRefExpr, and

Douglas Gregor e177b7254d Extend the use of QualifiedNameType to the creation of class template
specialization names. This way, we keep track of sugared types like

  std::vector<Real>

I believe we are now using QualifiedNameTypes everywhere we can. Next
step: QualifiedDeclRefExprs.

Douglas Gregor 5253768ada Introduce a representation for types that we referred to via a
qualified name, e.g., 

  foo::x

so that we retain the nested-name-specifier as written in the source
code and can reproduce that qualified name when printing the types
back (e.g., in diagnostics). This is PR3493, which won't be complete
until finished the other tasks mentioned near the end of this commit.

The parser's representation of nested-name-specifiers, CXXScopeSpec,
is now a bit fatter, because it needs to contain the scopes that
precede each '::' and keep track of whether the global scoping
operator '::' was at the beginning. For example, we need to keep track
of the leading '::', 'foo', and 'bar' in
 
  ::foo::bar::x

The Action's CXXScopeTy * is no longer a DeclContext *. It's now the
opaque version of the new NestedNameSpecifier, which contains a single
component of a nested-name-specifier (either a DeclContext * or a Type
*, bitmangled). 

The new sugar type QualifiedNameType composes a sequence of
NestedNameSpecifiers with a representation of the type we're actually
referring to. At present, we only build QualifiedNameType nodes within
Sema::getTypeName. This will be extended to other type-constructing
actions (e.g., ActOnClassTemplateId).

Also on the way: QualifiedDeclRefExprs will also store a sequence of
NestedNameSpecifiers, so that we can print out the property
nested-name-specifier. I expect to also use this for handling
dependent names like Fibonacci<I - 1>::value.

Ted Kremenek b36e01d87e Fix crash reported in <rdar://problem/6695527>. We now have
SVal::GetRValueSymbolVal do the checking if we can symbolicate a type instead of
having BasicStoreManager do it (which wasn't always doing the check
consistently). Having this check in SVal::GetRValueSymbolVal keeps the check in
one centralized place.
