This patch is extracted from D96035, it adds support for the existing DWARFLinker functionality. What is not supported yet: 1. Types deduplication(--odr mode). 2. Modules deduplication. 3. Generation of index tables. Reland2: temporarily disabled call to "--linker llvm" for tls-variable.test and location-expression.test as it does not work properly on bigendian architecture.

# This test verifies that an empty range list in the .debug_ranges section
|
|
# doesn't crash dsymutil. As clang does not produce this kind of debug
|
|
# info anymore, we used this hand-crafted assembly file to produce a testcase
|
|
# Compile with:
|
|
# llvm-mc -triple x86_64-apple-darwin -filetype=obj -o 1.o empty_range.o
|
|
|
|
# RUN: dsymutil --linker llvm -f -y %p/../dummy-debug-map.map -oso-prepend-path %p/../../Inputs/empty_range -o - | llvm-dwarfdump -debug-info - | FileCheck %s
