Based off of the patch in PR3342.  (This doesn't implement -Wno-pointer-sign,
but I don't know the driver code very well.)

If the SemaExpr changes are wrong or break existing code, feel free to

where F is a typedef of a function type, then the function "f" has a
prototype. This is a slight tweak to Chris's suggested fix in
PR3817. Fixes PR3817 and PR3840.

really horrible extensions that are disabled by default but that can
be accepted by -fheinous-gnu-extensions (but which always emit a 
warning when enabled).

As our first instance of this, implement PR3788/PR3794, which allows
non-lvalues in inline asms in contexts where lvalues are required. bleh.

This solution is much simpler (and doesn't add any per-scope overhead, which concerned Chris). 

The only downside is the LabelMap is now declared in two places (Sema and BlockSemaInfo). My original fix tried to unify the LabelMap in "Scope" (which would support nested functions in general). In any event, this fixes the bug given the current language definition. If/when we decide to support GCC style nested functions, this will need to be tweaked.

Remove ActiveScope (revert http://llvm.org/viewvc/llvm-project?view=rev&revision=65694 and http://llvm.org/viewvc/llvm-project?view=rev&revision=66741).

Will replace with something better today...

(which is bad), and now we don't.

This fix is partial because we don't do the end-of-translation-unit
initialization for tentative definitions that don't ever have any
initializers specified.
