Add stack protector support to clang. This generates the 'ssp' and 'sspreq'
function attributes. There are predefined macros that are defined when stack
protectors are used: __SSP__=1 with -fstack-protector and __SSP_ALL__=2 with
-fstack-protector-all.

Add another workaround for -include.
- If we don't find a file looking relative to the current working
directory, fall back to header search. This is closer to what would
happen if the lookup was starting from right directory in the first
place (except it will find files in the directory of the main
source file, which I *think* should not be found).

Fix rdar://6814950 - stdint.h isn't "-pedantic -std=c89" clean,
by marking the predefines buffer as a system header. The problem
with stdint is that it was getting problems like this:

/Volumes/Projects/cvs/llvm/Debug/lib/clang/1.0/include/stdint.h:43:9: warning: 'long long' is an extension when C99 mode is not enabled
typedef __INT64_TYPE__ int64_t;
^
<built-in>:73:29: note: instantiated from:
#define __INT64_TYPE__ long long
^

We correctly silence warnings in system headers, but only if the
spelling location of the token came from the system header. This is
designed so that if you use a system macro in your code that you don't
get punished for its definition. This is all cool except that the
predefines buffer wasn't considered a system header.
