of local anonymous unions as local variables.

Besides being morally wrong, the existing representation using local
variables breaks internal assumptions about the local variables' storage
size.

Compiling

```
   void fn1() {

     };
     i = c;

the 32-bit storage for the "local variable" c into two pieces because the
second piece is clearly outside the 8-bit range that is expected for a
variable of type char. Given the choice I'd rather fix the debug
representation than weaken the verifier.

Debuggers generally already know how to deal with anonymous unions when
they are members of C++ record types, but they may have problems finding
the local anonymous struct members in the expression evaluator.

[SEH] Add 32-bit lowering code for __try

This is just the clang-side of 32-bit SEH. LLVM still needs work, and it
will determinstically fail to compile until it's feature complete.

On x86, all outlined handlers have no parameters, but they do implicitly
take the EBP value passed in and use it to address locals of the parent
frame. We model this with llvm.frameaddress(1).

This works (mostly), but __finally block inlining can break it. For now,
we apply the 'noinline' attribute. If we really want to inline __finally
blocks on 32-bit x86, we should teach the inliner how to untangle
frameescape and framerecover.

Promote the error diagnostic from codegen to sema. It now rejects SEH on
non-Windows platforms. LLVM doesn't implement SEH on non-x86 Windows
platforms, but there's nothing preventing it.

Sean Callanan [Tue, 28 Apr 2015 18:41:46 +0000 (18:41 +0000)]
Implemented ASTImporter support for Stmts and fixed
some bugs in the ASTImporter that this exposed:

- When importing functions, the body (if any) was
  previously ignored.  This patch ensures that the
  body is imported also.

- When a function-local Decl is imported, the first
  thing the ASTImporter does is import its context
  (via ImportDeclParts()).  This can trigger
  importing the Decl again as part of the body of
  the function (but only once, since the function's
  Decl has been added to ImportedDecls).  This patch
  fixes that problem by extending ImportDeclParts()
  to return the imported Decl if it was imported as
  part of importing its context, and the patch adds
  ASTImporter::GetAlreadyImportedOrNull() to support
  this query.  All callers of ImportDeclParts return
  the imported version of the Decl if ImportDeclParts()
  returns it.

- When creating functions, InnerLocStart of the source
  function was re-used without importing.  This is a
  straight up bug, and this patch makes ASTImporter
  import the InnerLocStart and use the imported version.

- When importing FileIDs, the ASTImporter previously
  always tried to re-load the file for the corresponding
  CacheEntry from disk.  This doesn't work if the
  CacheEntry corresponds to a named memory buffer.  This
  patch changes the code so that if the UniqueID for the
  cache entry is invalid (i.e., it is not a disk file)
  the whole entry is treated as if it were invalid, which
  forces an in-memory copy of the buffer.
