indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.

It iterates over all the redeclarations, regardless of the starting point. For example:

1) int f();
2) int f();
3) int f();

if you have the (2) FunctionDecl and call redecls_begin/redecls_end to iterate, you'll get this sequence:
(2)
(1)
(3)

The motivation to introduce this was that, previously, if (3) was a function definition,
and you called getBody() at (2), it would not return it, since getBody() iterated over the previous declarations only,
so it would only check (2) and (1).

For multiple redeclarations they return the last one.

Also, add some non const versions of methods.

Ok, this is a bit out of place since C++ support is way way off, but it was just too cool to not show it off :-)

- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function.
- C++ out-of-line method definitions didn't get an access specifier.

Both were exposed by a crash when emitting a C++ method to a PCH file (assert at Decl::CheckAccessDeclContext()).

 - Previously this would crash on recursive types, and it was also incorrectly
   stripping off a level of indirection.
 - I'm not 100% convinced this is all correct, but it should be a monotonic
   improvment.

invalidate the region correctly. It uses the cast-to type to invalidate 
the region when available. To avoid invalid cast-to type like 'void*' or 'id',
region store now only records non-generic casts of regions.

works similar to isLoopInvariant, except that it will do trivial
hoisting to try to make the value loop invariant if it isn't already.
This makes it easier for transformation passes to clear trivial
instructions out of the way (the regular LICM pass doesn't run
until relatively late). This is code factored out of LoopSimplify
and other places.

Fix pr4544. When remating, make sure the destination register fits the instruction definition. It may be mismatched due to sub-register coalescing. 
No test case yet because the code doesn't trigger until 75408 is re-applied.

how we need more refactoring in the custom-check logic.
