where the descriptor took a pointer to an object and
expected the Initialize function to dereference that
pointer and extract the isa value.  This caused one
of our tests to fail.

external visible decls, call DeclContext::setMustBuildLookupTable so that the
"lazy decls" bit of the LookupPtr is set.

Previously, in non-C++, if there were no new declarations causing the "lazy decls" bit
to be set, then DeclContext::lookups_begin() would fail to return the decls from the PCH.

The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

their implementations are unavailable.  Start by simulating dispatch_sync().

This change is largely a bunch of plumbing around something very simple.  We
use AnalysisDeclContext to conjure up a fake function body (using the
current ASTContext) when one does not exist.  This is controlled
under the analyzer-config option "faux-bodies", which is off by default.

The plumbing in this patch is largely to pass the necessary machinery
around.  CallEvent needs the AnalysisDeclContextManager to get
the function definition, as one may get conjured up lazily.

BugReporter and PathDiagnosticLocation needed to be relaxed to handle
invalid locations, as the conjured body has no real source locations.
We do some primitive recovery in diagnostic generation to generate
some reasonable locations (for arrows and events), but it can be
improved.

not correctly store the contents of Objective-C
classes.  This was due to a combination of
factors:

  1) Types were only being completed if we were
     looking inside them for specific ivars
     (using FindExternalVisibleDeclsByName). 
     We now look the complete type up at every
     FindExternalLexicalDecls.

  2) Even if the types were completed properly,
     ValueObjectConstResult overrode the type
     of every ValueObject using the complete type
     for its class from the debug information.
     Superclasses of complete classes are not
     guaranteed to be complete.  Although "frame
     variable" uses the debug information,
     the expression parser does now piece together
     complete types at every level (as described
     in Bullet 1), so I provided a way for the
     expression parser to prevent overriding.

  3) Type sizes were being miscomputed by
     ClangASTContext.  It ignored the ISA pointer
     and only counted fields.  We now correctly
     count the ISA in the size of an object.

A PHI can't create interference on its own. If two live ranges interfere
at a PHI, they must also interfere when leaving one of the PHI
predecessors.

The old-fashioned many-to-one value mapping doesn't always work when
merging vector lanes. A value can map to multiple different values, and
it can even be necessary to insert new PHIs.

When a value number is defined by a copy from a value number that
required SSa update, include the live range of the copied value number
in the SSA update as well. It is not necessarily a copy of the original
value number any longer.

We already have HoistThenElseCodeToIf, this patch implements
SinkThenElseCodeToEnd. When END block has only two predecessors and each
predecessor terminates with unconditional branches, we compare instructions in
IF and ELSE blocks backwards and check whether we can sink the common
instructions down.

but can be dereferenced to form an expression which does have viable begin/end
functions, then typo-correct the range, even if something else goes wrong with
the statement (such as inaccessible begin/end or the wrong type of loop
variable).

In order to ensure we recover correctly and produce any followup diagnostics in
this case, redo semantic analysis on the for-range statement outside of the
diagnostic trap, after issuing the typo-correction.
