Convert ArchSpec::ParseMachOCPUDashSubtypeTriple to use StringRef.
This makes the code easier to grok, and since this is a very low
level function it also is very helpful to have this take a StringRef
since it means anyone higher up the chain who has a StringRef would
have to first convert it to a null-terminated string. This way it
can work equally well with StringRefs or const char*'s, which will
enable the conversion of higher up functions to StringRef.

GPGPU: Do not assume arrays start at 0
Our alias checks precisely check that the minimal and maximal accessed elements
do not overlap in a kernel. Hence, we must ensure that our host <-> device
transfers do not touch additional memory locations that are not covered in
the alias check. To ensure this, we make sure that the data we copy for a
given array is only the data from the smallest element accessed to the largest
element accessed.
We also adjust the size of the array according to the offset at which the array
is actually accessed.
An interesting result of this is: In case array are accessed with negative
subscripts ,e.g., A[-100], we automatically allocate and transfer _more_ data to
cover the full array. This is important as such code indeed exists in the wild.

[ARM] Promote small global constants to constant pools
If a constant is unamed_addr and is only used within one function, we can save
on the code size and runtime cost of an indirection by changing the global's storage
to inside the constant pool. For example, instead of:
ldr r0, .CPI0
bl printf
bx lr
.CPI0: &format_string
format_string: .asciz "hello, world!\n"
We can emit:
adr r0, .CPI0
bl printf
bx lr
.CPI0: .asciz "hello, world!\n"
This can cause significant code size savings when many small strings are used in one
function (4 bytes per string).
This recommit contains fixes for a nasty bug related to fast-isel fallback - because
fast-isel doesn't know about this optimization, if it runs and emits references to
a string that we inline (because fast-isel fell back to SDAG) we will end up
with an inlined string and also an out-of-line string, and we won't emit the
out-of-line string, causing backend failures.

Revert r280944 - Added 'inline' attribute to basic_string's destructor
This patch causes a couple of issues:
1) It triggers http://llvm.org/PR30341. Although the bug is not truly a libc++
bug it breaks the LLVM build using libc++. Reverting this patch is only
a temporary workaround until Clang is fixed.
2) It adds yet another ABI incompatibility when libc++.so is compiled with GCC.
Specifically GCC doesn't ignore the _LIBCPP_INLINE_VISIBILITY on the out-of-line
definition when compiling the dylib. This causes the externally instantiated
~basic_string symbol to have hidden visibility.
This patch should be recommitted after addressing (1) and (2). (2) can be fixed
by adding _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY which is defined as
__attribute__((visibility("default"), always_inline)) as opposed to
_LIBCPP_INLINE_VISIBILITY which makes the symbol hidden.

[MC] Handle discardable COFF sections in assembly
Summary:
This fixes a dumpbin warning on objects produced by the MC assembler
when starting from text. All .debug$S sections are supposed to be marked
IMAGE_SCN_MEM_DISCARDABLE. The main, non-COMDAT .debug$S section had
this set, but any comdat ones were not being marked discardable because
there was no .section flag for it.
This change does two things:
- If the section name starts with .debug, implicitly mark the section as
discardable. This means we do the same thing as gas on .s files with
DWARF from GCC, which is important.
- Adds the 'D' flag to the .section directive on COFF to explicitly say
a section is discardable. We only emit this flag if the section name
does not start with .debug. This allows the user to explicitly tweak
their section flags without worrying about magic section names.
The only thing you can't do in this scheme is to create a
non-discardable section with a name starting with ".debug", but
hopefully users don't need that.

Fix auto-upgrade of TBAA tags in Bitcode Reader
If TBAA is on an intrinsic and it gets upgraded, it'll delete the call
instruction that we collected in a vector. Even if we were to use
WeakVH, it'll drop the TBAA and we'll hit the assert on the upgrade
path.
r263673 gave a shot to make sure the TBAA upgrade happens before
intrinsics upgrade, but failed to account for all cases.
Instead of collecting instructions in a vector, this patch makes it
just upgrade the TBAA on the fly, because metadata are always
already loaded at this point.
