 - Only handles cases with @try with no @catch blocks, and there are a
   number of problems with the implementation. Nevertheless, this is
   good enough to handled @synchronized correctly, and some other
   basic uses.

Pass the CodeGenModule object to GenerateBlockFunction, instead of *this (which will call the copy constructor). 

Also, since we're creating a new CodeGenFunction object for each block function, we don't need to clear the BreakContinueStack.

Fix two @synchronized bugs found by inspection: the expression to sychronize on should only be evaluated once, and it is evaluated outside the cleanup scope.

Also, lift SyncEnter and SyncExit up in nervous anticipation of x86-64
zero cost EH.

  - When we are declaring a function in local scope, we can merge with
    a visible declaration from an outer scope if that declaration
    refers to an entity with linkage. This behavior now works in C++
    and properly ignores entities without linkage.
  - Diagnose the use of "static" on a function declaration in local
    scope.
  - Diagnose the declaration of a static function after a non-static
    declaration of the same function.
  - Propagate the storage specifier to a function declaration from a
    prior declaration (PR3425)
  - Don't name-mangle "main"

Also, make sure to pass <1 x i64> as i64 (not <1 x i64>, which doesn't
quite work yet in the backend).

CodeGen.  I'm not sure whether this actually makes any visible
