Removing the assertion is safe to do because any module level inline
assembly is always emitted first via AsmPrinter::doInitialization().

Summary:
The code in SelectionDAG did not handle the case where the
register type and output types were different, but had the same size.

For the locale refactor, the locale management functions (newlocale,
freelocale, uselocale) are needed in a separate header from the various _l
functions. This is because some platforms implement the _l functions in terms
of a locale switcher RAII helper, and the locale switcher RAII helper needs
the locale management functions. This patch helps pave the way by getting all
the functions in the right files, so that later diffs aren't completely
horrible.
Unfortunately, the Windows, Cygwin, and MinGW builds seemed to have
bit-rotted, so I wasn't able to test this completely. I don't think I made
things any worse than they already are though.

Summary: In some cases it can be proved statically that multidimensional array section refer to contiguous storage and can therefore be allowed in a map clause. This patch adds support for those cases in SEMA.

Instead of checking _LIBCPP_LOCALE_L_EXTENSIONS all over, instead check it
once, and define the various *_l symbols once. The private redirector symbol
names are all prefixed with _libcpp_* so that they won't conflict with user
symbols, and so they won't conflict with future C library symbols. In
particular, glibc likes providing private symbols such as __locale_t, so we
should follow a different naming pattern (like _libcpp_*) to avoid problems
on that front.
Tested on Linux with glibc. Hoping for the best on OSX and the various BSDs.

Original patch by Stefan Bühler http://reviews.llvm.org/D12834
Difference between original and this one:
- fixed all comments in original code review
- added more tests, all new diagnostics now covered by tests
- moved abi_tag on re-declaration checks to Sema::mergeDeclAttributes
where they actually may work as designed
- clang-format + other stylistic changes
Mangle part will be sent for review as a separate patch.

Original commit message:
calculate builtin_object_size if argument is a removable pointer
This patch fixes calculating correct value for builtin_object_size function
when pointer is used only in builtin_object_size function call and never
after that.

Reland the original change with a small modification (first do a null check
and then do the cast) to satisfy ubsan.

Until now the only exception APIs supported by gcc_personality_v0
are DWARF EH and SJLJ. This adds support for ARM EHABI as well.
This is achieved by
a) changing the function signature on ARM EHABI,
b) unwinding the stack before returning _URC_CONTINUE_UNWIND.
See "Exception Handling ABI for the ARM Architecture" for details
(http://infocenter.arm.com/help/topic/com.arm.doc.ihi0038b/IHI0038B_ehabi.pdf).

We changed several functions in LoopAccessAnalysis to use PSE instead of
taking SE and a SCEV predicate as arguments, but didn't update the comments.
This also fixes a comment in ScalarEvolution, where we refered to Preds
when the argument name was A.

Supprot DPP syntax as used in SP3 (except several operands syntax).
Added dpp-specific operands in td-files.
Added DPP flag to TSFlags to determine if instruction is dpp in InstPrinter.
Support for VOP2 DPP instructions in td-files.
Some tests for DPP instructions.
ToDo:
- VOP2bInst:
- vcc is considered as operand
- AsmMatcher doesn't apply mnemonic aliases when parsing operands
- v_mac_f32
- v_nop
- disable instructions with 64-bit operands
- change dpp_ctrl assembler representation to conform sp3

OpenMP 4.5 allows privatization of non-static data members in OpenMP

This patch extends the -fuse-ld option to accept a full path to an executable
and use it verbatim to invoke the linker. There are generally two reasons
to desire this.
The first reason relates to the sad truth is that Clang is retargetable,
Binutils are not.
While any Clang from a binary distribution is sufficient to compile code
for a wide range of architectures and prefixed BFD linkers (e.g.
installed as /usr/bin/arm-none-linux-gnueabi-ld) as well as cross-compiled
libc's (for non-bare-metal targets) are widely available, including on all
Debian derivatives, it is impossible to use them together because
the -fuse-ld= option allows to specify neither a linker prefix nor
a full path to one.
The second reason is linker development, both when porting existing linkers
to new architectures and when working on a new linker such as LLD.

Summary:
Is there any other code needed for correctly handling appending linkage?
Do we need to do something more with @llvm.global_ctors in
SymbolTable.cpp:addBitcodeFile; otherwise the combined bitcode module
won't have all the global ctors.

It is a transitive dependency, so static build are OK but not build
with individual DSO for each LLVM library.
