containing a DoStmt, and the LHS doesn't create a new block, then we should
return RBlock.  Otherwise we'll incorrectly return NULL.

Also relax an assertion in VisitWhileStmt(). Reset 'Block' when it is finished.

There's probably still significant padding waste on x86-64 UNIXen, but
the difference in 32-bit compiles should be significant.

There are a lot of Expr nodes left that could lose a word this way.

Emacs regression due to my recent change that expanded type-checking
in the presence of K&R function definitions.

  - tags with C linkage should ignore visibility=hidden
  - functions and variables with explicit visibility attributes should
    ignore the linkage of their types
Either of these should be sufficient to fix PR8457.

Also, FileCheck-ize a test case.

covariant/contravariant overrides and implementations, but do so under
control of a new flag (-Wno-objc-covariant-overrides, which yes does cover
contravariance too).

*At least* the covariance cases will probably be enabled by default shortly,
but that's not totally uncontroversial.

getCanonicalType() to make sure that the type we got back is actually
canonical. This is the case for most types, which always build a
canonical type when given canonical components. However, some types that
involve expressions in their canonicalization (e.g., array types with
dependent sizes) don't always build canonical types from canonical
components, because there is no such thing as a "canonical"
expression. Therefore, we do this extra mapping to ensure that the
canonical types we store are actually canonical.

Fix lazy symbolication bug in RegionStore involving fields of global variables.  When invalidated, the entire
globals memory space gets assigned a symbolic value, but that value was not being used for lazy symbolication
of fields of globals.  This could result in cases where bogus null dereferences were being reported.

Fixes PR 8440.
