Fix two pedantic issues with our builtin headers. The __STDC_VERSION__
...
for C99 is '199901L' and we shouldn't be comparing it with anything
else.
Neither of these should have had any impact in practice.

Remove a broken attempt to cope with someone #undef'ing __has_include_next.
...
This was broken because __has_include_next(...) would not be valid in a
preprocessor condition if __has_include_next is not defined.

Define [U]LLONG_{MIN,MAX} for C++11, add tests.

Add tests for limits.h, not just [U]LLONG_{MIN,MAX}.

Remove WCHAR_MIN and WCHAR_MAX from limits.h. According to posix and c99
...
these should be in stdint.h - and they already are.
Fixes rdar://10097036.

Implement a __WCHAR_UNSIGNED__ macro and use it to include WCHAR_MIN and
...
WCHAR_MAX in limits.h, thus solving the problem where the system header
thinks it knows better.

Futher reduce the includes of our builtin headers, and teach limits.h to avoid
...
include_next when not hosted or unavailable. This follows the pattern in
stdint.h and allows these headers to work even in a freestanding configuration
without a standard library.

Fix limits.h for linux, as glibc does a #include_next unless
...
_GCC_LIMITS_H_ is defined, when __GNUC__ is defined.
Also, we need to stay away from possible conflicts with header guards.
We should use CLANG_ to prefix all header guards.

only define MB_LEN_MAX if the system <limits.h> doesn't.
...
don't typecast CHAR_MIN to char, this makes it not a PP constant
and gives it the wrong unpromoted type. Thanks to Sebastian for
pointing this out!
