Add support for Swift reflection metadata to dsymutil. This patch adds support for copying Swift reflection metadata (__swift5_.* sections) from .o files to into the symbol-rich binary in the output .dSYM. The functionality is automatically enabled only if a .o file has reflection metadata sections and the binary doesn't. When copying dsymutil moves the section from the __TEXT segment to the __DWARF segment. rdar://76973336 Differential Revision: https://reviews.llvm.org/D115007

# How to generate this file:
|
|
# 1. First take a swift file and run xcrun swiftc -g -v file.swift
|
|
# secondfile.swift, make sure the two swift files are in a short path like /tmp/
|
|
|
|
# 2. Now you can see what the driver does, generate the object files in the
|
|
# tmp directory
|
|
|
|
# 3. Run obj2yaml on object file to create a yaml file
|
|
|
|
# 4. I ran delta to reduce this file.
