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.

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.
Patch by Strahinja Petrovic.

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

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

s_setpc_b64 has just one 64-bit source which is the address of instruction to jump to.

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

This implements a very simple conservative transformation that doesn't
require more than linear code size growth. There's room for much more
optimization in this space.

Building on the previous change, this generalizes
ScalarEvolution::getRangeViaFactoring to work with
{Ext(C?A:B)+k0,+,Ext(C?A:B)+k1} where Ext can be a zero extend, sign
extend or truncate operation, and k0 and k1 are constants.

This is intended to provide a parallel (threaded) ThinLTO scheme
for linker plugin use through the libLTO C API.
The intent of this patch is to provide a first implementation as a
proof-of-concept and allows linker to start supporting ThinLTO by
definiing the libLTO C API. Some part of the libLTO API are left
unimplemented yet. Following patches will add support for these.
The current implementation can link all clang/llvm binaries.

Add a missing include. This is important in the case HandleLLVMOptions is
included prior to the missing CheckCXXSourceCompiles or CheckCXXCompilerFlag
which includes CheckCXXSourceCompiles.

The fix consisting in using the library call for atomic compare and swap when
the instruction is not safe to use may be incorrect. Indeed the library call may
not exist on all platform. In other words, we need a better fix!
