Previously, many error messages would simply be "read-only variable is not
assignable" This change provides more information about why the variable is
not assignable, as well as note to where the const is located.

We had two bugs:
- We wouldn't properly warn when a struct/union/enum was mentioned
inside of a record definition if no declarator was provided. We
should have mentioned that this declaration declares nothing.
- We didn't properly support Microsoft's extension where certain
declspecs without declarators would act as anonymous structs/unions.
* We completely ignored the case where such a declspec could be a
union.
* We didn't properly handle the case where a record was defined inside
another record:
struct X {
int a;
struct Y {
int b;
};
};

destination type for initialization, assignment, parameter-passing,
etc. The main issue fixed here is that we used rather confusing
wording for diagnostics such as
t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
expected 'char *' [-pedantic]
char *name = __func__;
^ ~~~~~~~~
We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:
t.c:2:9: warning: initializing 'char *' from an expression of type
'char const [2]' discards qualifiers [-pedantic]
char *name = __func__;
^ ~~~~~~~~

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

assertion when the ivars and method list was reset into the existing
interface. To fix this, mark decls as invalid when they are redefined,
and don't insert ivars/methods into invalid decls.

C++ handle anonymous structs/unions in the same way. Addresses several
bugs:
<rdar://problem/6259534>
<rdar://problem/6481130>
<rdar://problem/6483159>
The test case in PR clang/1750 now passes with -fsyntax-only, but
CodeGen for inline assembler still fails.
