  Log Message:
  -----------
  Emit swift5 reflection section data in dsym bundle generated by dsymutil in the Dwarf section.

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.
