Summary:
The tests for r362121 ran dsymutil against a test binary every time.
This caused problems on lld-x86_64-ubuntu-fast as dsymutil required
a lipo tool be available to process those binaries.
This change rewrites the new test cases in macho-disassemble-g-dsym
to use bespoke test binaries (exe and dwarf) simplifying the test's
runtime dependencies.
The changes to tools/llvm-objdump/MachODump.cpp are unchanged from
r362121

Summary:
Commonly programmers use llvm-objdump to disassemble Mach-O target
binaries with Mach-O dSYMS. While llvm-objdump allows programmers to
disassemble Universal binaries, it previously did not recognize
Universal dSYM files. This change updates llvm-objdump to support
passing in Universal files via the -dsym option. Now, when
disassembling a Mach-O file either as a stand alone file or as an entry
in a Universal binariy, llvm-objdump will search through a Universal
dSYM for a Mach-O matching the architecture flag of the file being
disassembled.

This change rewrites and splits reloc-types.test
to use yaml2obj instead of precompiled binaries.
That allowed to remove 7 precompiled objects from the inputs.
I took the existent objects, used obj2yaml on them, simplified the result and
used yaml2obj in the test case with the result.
Notes:
* I converted, but did not remove relocs.obj.elf-i386, relocs.obj.elf-x86_64 or relocs.obj.elf-mips objects
because found they are used in other tests.
* I was unable to convert relocs.obj.elf-ppc64, because obj2yaml hangs on this file for me.
* I was unable to convert relocs.obj.macho-arm, relocs.obj.macho-i386 and relocs.obj.macho-x86_64
because the output produced by obj2yaml does not seem to be correct.
* Because of the above I did not remove the script for creating all
of those objects: test\tools\llvm-readobj\Inputs\relocs.py

llvm/test/tools/llvm-objdump/X86/elf-disassemble-symbol-labels-rel.test
uses --implicit-check-not to verify that certain patterns do not occur
in llvm-objdump's output, except in places where they are explicitly
checked. Unfortunately, the patterns are generic enough that they may
be part of the file name which is also output by llvm-objdump. This
change matches the line with the filename explicitly so that the
implicit patterns are not applied to it.

This fixes PR41886: llvm-objdump -d -r -j .text doesn't show inline relocations of .text
While here, switch to stable_sort() because we don't want to change the order of relocations applied to the same location. gABI says consecutive relocation records are composed together and their order matters. In practise it is difficult to see relocations applied to the same location not consecutive, we just have to keep the relative order of relocations with the same offset.

This is a result of what I found during my work on https://bugs.llvm.org/show_bug.cgi?id=41679.
Previously LLVM readelf took the information about .dynamic section
from its PT_DYNAMIC segment only. GNU tools have a bit different logic.
They also use the information from the .dynamic section header if it is available.
This patch changes the code to improve the compatibility with the GNU Binutils.

When a LLVM binary such as llvm-*-fuzzer is built with libc++, it has dependency on libc++. The path to find shared libraries specified in llvm-*-fuzzer is relative. As a result, these binaries cannot be copied to an arbitrary directory and launched from there. Changes in this patch add a LIT feature to indicate that libc++ is used to build and, based on the feature exclude test cases that test by copying llvm-*-fuzzer binaries to a directory.
