Eric Christopher bd202c0496 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.

Alexis Hunt 8cb46bb51c 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.

Chandler Carruth 5eef9ba483 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.

Mike Stump 6b63074de9 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.

Chris Lattner 6fbf3a07bc 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!
