fix: forgot to commit the updated dwarfdump-test-zlib.elf-x86-64
Original commit message:
[llvm-dwarfdump] - Teach dwarfdump to decompress debug sections in zlib style.
Before this llvm-dwarfdump only recognized zlib-gnu compression style of headers,
this patch adds support for zlib style.
It looks reasonable to support both styles for dumping,
even if we are not going to suport generating of deprecated gnu one.

Patch by Nitesh Jain.
Summary: The type of Imm in MipsDisassembler.cpp was incorrect since SignExtend64 return int64_t type.As per the MIPSr6 doc ,the offset is added to the address of the instruction following the branch (not the branch itself), to form a PC-relative effective target address hence “4” is added to the offset. The offset of some test case are update to reflect the changes due to “ + 4 ” offset and new test case for negative offset are added.

Summary:
Following patch D19265 which enable software floating point support in the Sparc backend, this patch enables the option to be enabled in the front-end using the -msoft-float option.
The user should ensure a library (such as the builtins from Compiler-RT) that includes the software floating point routines is provided.

directives.
If firstprivate variable is is captured by value in outlined region and then used as firstprivate variable in inner worksharing directive, the copy for this firstprivate variable was not created. Fixed this bug.

Clang doesn't dllexport defaulted special member function defaulted
inside class but does it if they defaulted outside class. MSVC doesn't
make any distinction where they were defaulted. Also MSVC 2013 and 2015
export different set of members. MSVC2015 doesn't emit trivial defaulted
x-tors but does emit copy assign operator.

Thread through -fsjlj-exceptions to the backend via the TargetOptions. This is
in preparation for supporting SjLj exceptions on x86 (e.g. for MinGW).

Previously, we created a .bss section when needed. We had a function
ensureBss() for that purpose. Turned out that was error-prone
because it was easy to forget to call that function before accessing
the .bss section.
This patch always make the BSS section. The section is added to the
output when it's not empty.

Copy relocations are relocations to copy data from DSOs to
executable's .bss segment at runtime. It doesn't make sense to
create such relocations for zero-sized symbols.
GNU linkers don't agree with each other. ld rejects such
relocation/symbol pair. gold don't reject that but do not create
copy relocations as well. I took the former approach because
I don't think the latter is what user wants.

The statement constructed an anonymous structure which was typedefed. The
anonymous structure has internal linkage, and that would cause an error when
building with modules. Give the type declaration a tag name to address the
error when building with modules.

The logic that sets up lit features for sanitizers is largely copied
between here and clang, except clang's was fixed some time ago to
handle multiple sanitizers (ie, Asan + Ubsan). This just makes the
code in LLVM consistent with how it's done in clang to avoid any
gotchas by users of this.

Moved the ModuleLoader and supporting helper loadModuleFromBuffer out of
ThinLTOCodeGenerator and into new LTO.h/LTO.cpp files. This is in
preparation for a patch that will utilize these in the gold-plugin.
Note that there are some other pending patches (D20268 and D20290) that
also plan to refactor common interfaces and functionality into this same
pair of new files.

This changes IRCE to optimize uses, and not branches. This change is
NFCI since the uses we do inspect are in practice only ever going to be
the condition use in conditional branches; but this flexibility will
later allow us to analyze more complex expressions than just a direct
branch on a range check.

Both the (V)CVTDQ2PD(Y) (i32 to f64) and (V)CVTPS2PD(Y) (f32 to f64) conversion instructions are lossless and can be safely represented as generic __builtin_convertvector calls instead of x86 intrinsics without affecting final codegen.
This patch removes the clang builtins and their use in the sse2/avx headers - a future patch will deal with removing the llvm intrinsics, but that will require a bit more work.

Before r269750 we did the comparisons in this loop in signed ints so
that it DTRT when MinCSFrameIndex was 0. This was changed because it's
now possible for MinCSFrameIndex to be UINT_MAX, but that introduced a
bug when we were comparing `>= 0` - this is tautological in unsigned.
Rework the comparisons here to avoid issues with unsigned wrapping.
No test. I couldn't find a way to get any of the StackGrowsUp in-tree
targets to reach the code that sets MinCSFrameIndex.
