We currently diagnose static data members directly contained in unnamed classes,
but we should also diagnose when they're in a class that is nested (directly or
indirectly) in an unnamed class. Do this by iterating up the list of parent
DeclContexts and checking if any is an unnamed class.
Similarly also check for function or method DeclContexts (which includes things
like blocks and openmp captured statements) as then the class is considered to
be a local class, which means static data members aren't allowed.

MarkVarDeclODRUsed indirectly calls captureInBlock, which creates a copy
expression. The copy expression is insulated in it's own
ExpressionEvaluationContext, so it saves, mutates, and restores MaybeODRUseExprs
as CleanupVarDeclMarking is iterating through it, leading to a crash. Fix this
by iterating through a local copy of MaybeODRUseExprs.

The bug is that ExprCleanupObjects isn't always empty
in a fresh evaluation context. New evaluation contexts just
track the current depth of the stack.
The assertion will misfire whenever we finish processing
a function body inside an expression that contained an earlier
block literal with non-trivial captures. That's actually
a lot less likely than you'd think, though, because it has
to be a real function declaration, not just another block.
Mixed block/lambda code would work, as would a template
instantiation or a local class definition.
The code works correctly if the assertion is disabled.

picking up cleanups from earlier in the statement. Also fix a
crash-on-invalid where a reference to an invalid decl from an
enclosing scope was causing an expression to fail to build, but
only *after* a cleanup was registered from that statement,
causing an assertion downstream.
The crash-on-valid is rdar://13459289.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

specific targets default them to on. Default blocks to on on 10.6 and later.
Add a -fblocks option that allows the user to override the target's default.
Use -fblocks in the various testcases that use blocks.
