407e2124bf Extend -remap-file=from;to to permit mapping from a non-existent 
file. This is accomplished by introducing the notion of a "virtual"
file into the file manager, which provides a FileEntry* for a named
file whose size and modification time are known but which may not
exist on disk.

Added a cute little test that remaps both a .c file and a .h file it
includes to alternative files.

f8a04a1d6e Exit the command line into <built-in> instead of going directly from the command line to the input file. 
We passed <built-in> on the way in, so we should pass it again on the way out.

55c9877b66 Generalize stdint.h for non-8-bit-multiple types, patch by 
Ken Dyck!

"This adds definitions for types of 8-bit multiples
from 8 to 64 to stdint.h and rationalizes the selection of types 
for the exact-width definitions in InitPreprocessor.cpp."

2857ccbaa7 Fix for PR4192: fix the definition of int64_t on x86_64 Linux. 
Note that I'm guessing that *BSD and Solaris do the same thing as Linux 
here, but it's quite possible I'm wrong; if the following testcase 
gives an error on x86-64 with gcc for any of those operating systems, please
tell me:

#include <stdint.h>

int64_t x; long x;

d63bbadbef 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.
