Enable constexpr on Visual Studio 2015, add support for two equivalent attributes
Patch by Alexander Riccio
This patch enables `constexpr` on Visual Studio 2015 by adding `||

I also added the MSVC/SAL equivalent of:

- `__attribute__((returns_nonnull))` as an

[ThinLTO] Use MD5 hash in function index.
Summary:
This patch uses the lower 64-bits of the MD5 hash of a function name as
a GUID in the function index, instead of storing function names. Any
local functions are first given a global name by prepending the original
source file name. This is the same naming scheme and GUID used by PGO in
the indexed profile format.
This change has a couple of benefits. The primary benefit is size
reduction in the combined index file, for example 483.xalancbmk's
combined index file was reduced by around 70%. It should also result in
memory savings for the index file in memory, as the in-memory map is
also indexed by the hash instead of the string.
Second, this enables integration with indirect call promotion, since the
indirect call profile targets are recorded using the same global naming
convention and hash. This will enable the function importer to easily
locate function summaries for indirect call profile targets to enable
their import and subsequent promotion.
The original source file name is recorded in the bitcode in a new
module-level record for use in the ThinLTO backend pipeline.

unwind information during the conditional instruction block and when
we reach the end of it (first instruction with a differemt condition)
then we restore the unwind information we had before the condition.

This is an idea to make "thread step-in --target" work for the common
case where you have:
1 -> foo (bar(),
2 baz(),
3 lala());
4
You are sitting on line 1, and want to step into foo, but not bar, baz & lala. Unfortunately
there are line table entries for lines 1-3, and lldb doesn't know anything about the nesting
of statement in these lines. So we'll have to use the user's intelligence... This patch adds:
(lldb) thread step-in -t foo --end-line 4
That tells lldb to keep stepping in till line 4, but stop if you step into foo. I think I would
remember to use this when faced with some of the long gnarly call sequences in lldb. But there
might be ways I haven't thought of to make it more convenient. Jason suggests having "end" as a
special token for --end-line which just means keep going to the end of the function, I really want
to get into this thing...

[Orc] Add lazy-JITting support for i386.
This patch adds a new class, OrcI386, which contains the hooks needed to
support lazy-JITing on i386 (currently only for Pentium 2 or above, as the JIT
re-entry code uses the FXSAVE/FXRSTOR instructions).
Support for i386 is enabled in the LLI lazy JIT and the Orc C API, and
regression and unit tests are enabled for this architecture.

Fix overload sets of strchr, strpbrk, strrchr, memchr and strstr from
<string.h> and wcschr, wcspbrk, wcsrchr, wmemchr, and wcsstr from <wchar.h> to
provide a const-correct overload set even when the underlying C library does
not.
This change adds a new macro, _LIBCPP_PREFERRED_OVERLOAD, which (if defined)
specifies that a given overload is a better match than an otherwise equally
good function declaration without the overload. This is implemented in modern
versions of Clang via __attribute__((enable_if)), and not elsewhere.
We use this new macro to define overloads in the global namespace for these
functions that displace the overloads provided by the C library, unless we
believe the C library is already providing the correct signatures.

WholeProgramDevirt: introduce.
This pass implements whole program optimization of virtual calls in cases
where we know (via bitset information) that the list of callees is fixed. This
includes the following:
- Single implementation devirtualization: if a virtual call has a single
possible callee, replace all calls with a direct call to that callee.
- Virtual constant propagation: if the virtual function's return type is an
integer <=64 bits and all possible callees are readnone, for each class and
each list of constant arguments: evaluate the function, store the return
value alongside the virtual table, and rewrite each virtual call as a load
from the virtual table.
- Uniform return value optimization: if the conditions for virtual constant
propagation hold and each function returns the same constant value, replace
each virtual call with that constant.
- Unique return value optimization for i1 return values: if the conditions
for virtual constant propagation hold and a single vtable's function
returns 0, or a single vtable's function returns 1, replace each virtual
call with a comparison of the vptr against that vtable's address.
