2c54f42ad2 Use the cpuid 64 bit flag to pick the default CPU name for an unknown model. 
For the Family 6 switch in sys::getHostCPUName, an unrecognized model was
reported as "i686".  That's a really bad default since it means that new
CPUs will be treated as if they can only use 32-bit code.  This just looks
at the cpuid extended feature flag for 64 bit support, and if that is set,
it uses a default x86-64 cpu.  Similar logic is already used for the Family
15 code.  <rdar://problem/11314502>

4ca961430f This patch adds a new NVPTX back-end to LLVM which supports code generation for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it. 
The new target machines are:

nvptx (old ptx32) => 32-bit PTX
nvptx64 (old ptx64) => 64-bit PTX

The sources are based on the internal NVIDIA NVPTX back-end, and
contain more functionality than the current PTX back-end currently
provides.

9ddbe009a4 [Support/Unix] Unconditionally include time.h. 
When building LLVM on Linux with libc++ with CMake TIME_WITH_SYS_TIME is
undefined, and HAVE_SYS_TIME_H is defined. This ends up including
sys/time.h but not time.h. Unix/TimeValue.inc requires time.h for asctime_r
and localtime. libstdc++ seems to include time.h anyway, but libc++ does
not.

Fix this by always including time.h

3e90fea8d3 Conflict with st_dev/st_ino identifiers under Debian GNU/Hurd 
The problem is that the struct file_status on UNIX systems has two
members called st_dev and st_ino; those are also members of the
struct stat, and they are reserved identifiers which can also be
provided as #define (and this is the case for st_dev on Hurd).
The solution (attached) is to rename them, for example adding a
"fs_" prefix (= file status) to them.

ffa121d1ea SmallPtrSet: Reuse DenseMapInfo's pointer hash function instead of inventing a bad one ourselves. 
DenseMap's hash function uses slightly more entropy and reduces hash collisions
significantly.  I also experimented with Hashing.h, but it didn't gave a lot of
improvement while being much more expensive to compute.

f5736f87f2 In MemoryBuffer::getOpenFile() make sure that the buffer is null-terminated if 
the caller requested a null-terminated one.

When mapping the file there could be a racing issue that resulted in the file being larger
than the FileSize passed by the caller. We already have an assertion
for this in MemoryBuffer::init() but have a runtime guarantee that
the buffer will be null-terminated, so do a copy that adds a null-terminator.

Protects against crash of rdar://11161822.
