- Demonstrates how to build a standalone tool which loads source code using the
   Driver and Frontend libraries, and then uses CodeGen and the JIT to actually
   execute the code.

 - Still more complicated than it should be, but hey its only 153 lines. :)

keep track of instructions that return void) per-function. This fixes PR5278.

This breaks backwards compatibility with the metadata format. That's okay
because we haven't released the metadata bitcode yet.

splitting all the patterns under scope nodes into equality sets
based on their first node.  The second step is to rewrite the
graph info a form that exposes the sharing.  Before I do this, 
I want to redesign the Scope node.

types. Rank these conversions below other conversions. This allows overload
resolution when the only distinction is between a complex and scalar type. It
also brings the complex overload resolutin in line with GCC's.

which branch on undef to branch on a boolean constant for the edge
exiting the loop. This helps ScalarEvolution compute trip counts for
loops.

Teach ScalarEvolution to recognize single-value PHIs, when safe, and
ForgetSymbolicName to forget such single-value PHI nodes as apprpriate
in ForgetSymbolicName.

format is not parsable, even if the module is legal. To get parsable output,
dump the module instead of the function or smaller, since metadata kind are
attached to the module (not the context).

This patch implements the CallEnter/CallExit idea of Ted.

Add two interfaces to GRSubEngine: ProcessCallEnter, ProcessCallExit.

The CallEnter program point uses caller's location context. The
CallExit program point uses callee's location context.

CallEnter is built by GRStmtNodeBuilder. CallExit is built by
GREndPathNodeBuilder.

gradually be migrated here.

As a first check, check that when 'dispatch_once()' is passed a predicate value
that has non-local storage.

class types, dependent types, and namespaces. I had previously
weakened this invariant while working on parsing pseudo-destructor
expressions, but recent work in that area has made these changes
unnecessary.

This is the way I would like to move the frontend function towards -- distinct
pieces of functionality should be exposed only via FrontendAction
implementations which have clean and relatively-stable APIs.

This also isolates the surface area in clang which depends on LLVM CodeGen.

expressions that look like pseudo-destructors, e.g.,

  p->T::~T()

where p has dependent type.

At template instantiate time, we determine whether we actually have a
pseudo-destructor or a member access, and funnel down to the
appropriate routine in Sema.

Fixes PR6380.
