Both methods need to clear out existing bindings and provide a new default
binding. Originally KillStruct always provided UnknownVal as the default,
but it's allowed symbolic values for quite some time (for handling returned
structs in C).
No functionality change.

This should speed up activities that need to access bindings by cluster,
such as invalidation and dead-bindings cleaning. In some cases all we save
is the cost of building the region cluster map, but other times we can
actually avoid traversing the rest of the store.
In casual testing, this produced a speedup of nearly 10% analyzing SQLite,
with /less/ memory used.

This makes it faster to access and invalidate bindings with symbolic offsets
by only computing this information once.
No intended functionality change.

This was triggering -Woverloaded-virtual, but there's really no reason for
the cast version to be virtual anyway. It just calls through to the QualType
entry point.

An ASTContext's RecordLayoutInfo can only be used to look up offsets of
direct base classes, and we need the offset to make non-symbolic bindings
in RegionStore. This change makes sure that we have one layer of
CXXBaseObjectRegion for each base we are casting through.
This was causing crashes on an internal buildbot.

rebuilds to serially link each tool, which is really really slow.
We still have to build libclang serially first because c-index-test
depends on it.

Remove Escaped state, which is not really necessary. We can just stop
tracking the symbol instead of keeping it around and marking escaped.

This is an initial (unoptimized) version. We split the path when
inlining ObjC instance methods. On one branch we always assume that the
type information for the given memory region is precise. On the other we
assume that we don't have the exact type info. It is important to check
since the class could be subclassed and the method can be overridden. If
we always inline we can loose coverage.
Had to refactor some of the call eval functions.

out.
Unfortunately, the existing makefiles for the extra repo don't specify
the correct library dependencies. Fixing that next. If you're following
along, you'll get linker errors.

We handled the builtin version of this function in r157968, but the builtin
isn't used when compiling as -fno-constant-cfstrings.
This should complete <rdar://problem/6157200>.

are not definitions. This follows the behavior of both gcc and earlier
versions of clang. Regression from r156531. <rdar://problem/12048621>.
