glibc < 2.18 is C99 compliant and only provides the format macros in C++ if
__STDC_FORMAT_MACROS is defined. This change fixes the debug build for
GCC 4.8, GCC 6.2 and Clang 3.9.1 that were previously broken on my machine.
It shows no regression for libc++ >= 4.0.0 which has a fix since September:

This had significant negative consequences and I don't have a good
solution for it yet.

var string =
[
'aaaaaa',
'bbbbbb',

.join('+');
After:
var string = [

Accounts for a case that caused an assertion failure by attempting to
query for the vtable linkage of a non-dynamic type.t
This reverts commit r292801.

By calling getScalarizationOverhead with the CallInst instead of the types of
its arguments, we make sure that only unique call arguments are added to the
scalarization cost.
getScalarizationOverhead() is extended to handle calls by only passing on the
actual call arguments (which is not all the operands).
This also eliminates a wrapper function with the same name.

First pass at generating weak definitions of inline functions from module files
(& skipping (-O0) or emitting available_externally (optimizations)
definitions where those modules are used).
External functions defined in modules are emitted into the modular
object file as well (this may turn an existing ODR violation (if that
module were imported into multiple translations) into valid/linkable
code).
Internal symbols (static functions, for example) are not correctly
supported yet. The symbol will be produced, internal, in the modular
object - unreferenceable from the users.

These member functions were decorated with `_LIBCPP_FUNC_VIS` when the
class is also decorated with external visibility. This breaks down when
building for PE/COFF, where the member function cannot be decorated if
it is within a decorated class. The class attribute will propagate to
the member. Remove the extraneous decoration.

Microsoft's SAL has a `__deref` macro which results in a compilation
failure when building the filesystem module on Windows. Rename the
member function internally to avoid the conflict.

Previously this test case fired an assertion in getNode because we tried to create an insert_subvector with both input types the same size and the index pointing to half the vector width.

Support for CUDA printf is exploited to support printf for
an NVPTX OpenMP device.
To reflect the support of both programming models, the file
CGCUDABuiltin.cpp has been renamed to CGGPUBuiltin.cpp, and
the call EmitCUDADevicePrintfCallExpr has been renamed to
EmitGPUDevicePrintfCallExpr.

Add "OPTIONAL" comment to declaration of weak function in the internal

`interface_symbols_darwin.c` which were failing after r293423.

The primary use of the dump() functions in LLVM is for use in a
debugger. Unfortunately lldb does not seem to handle default arguments
so using `p SomeMI.dump()` fails and you have to type the longer `p
SomeMI.dump(nullptr)`. Remove the paramter to make the most common use
easy. (You can always construct something like `p
SomeMI.print(dbgs(),MyTII)` if you need more features).

This causes unnecessary warnings when building with `cl`. Newer
versions of the C standard permit the redefinition of the macro to the
same value (which is the case here), unfortunately, `cl` does not yet
implement this. Add a check to prevent the redefinition.

Replaces an xor+movd/movq with an xorps which will be shorter in codesize, avoid an int-fpu transfer, allow modern cores to fast path the result during decode and helps other combines recognise an all-zero vector.
The only reason I can think of that we'd want to keep scalar_to_vector in this case is to help recognise the upper elts are undef but this doesn't seem to be a problem.

While this probably should be considered a dump debugger utility, the C
API currently has no other ways to print a module to stderr for error
reporting purposes, so keep it even in release builds.

PACKUSWB converts Signed word to Unsigned byte, (the same about DW) and it can't be used for umin+truncate pattern.
AVX-512 VPMOVUS* instructions fit the pattern since they convert Unsigned to Unsigned.

This arranges the static helpers in an order where they are defined
prior to their use to avoid the need of forward declarations, and
collect the core pass components at the bottom below their helpers.
This also folds one trivial function into the pass itself. Factoring
this 'runImpl' was an attempt to help porting to the new pass manager,
however in my attempt to begin this port in earnest it turned out to not
be a substantial help. I think it will be easier to factor things
without it.
This is an NFC change and does a minimal amount of edits over all.
Subsequent NFC cleanups will normalize the formatting with clang-format
and improve the basic doxygen commenting.
