  -----------
  [llvm-readobj] [COFF] Cope with debug directory payloads in unmapped areas

According to the spec, the payload for debug directories can be
in parts of the binary that aren't mapped at runtime - in these
cases, AddressOfRawData is just set to zero.

  Log Message:
  -----------
  [llvm-objcopy] [COFF] Fix a misconception about debug directory payloads

The debug directory payload is not located directly after the
debug directory entry itself, but can essentially be located anywhere
in the binary (even outside of mapped sections, although we don't
handle that case).

  Log Message:
  -----------
  [clang] [MinGW] Add the compiler rt libdirs to the search path

This matches what is done for MSVC in
b8000c0ce84541c5b5535419234fb65ce77d6756. Since that commit, compiler
rt sanitizer libraries aren't linked to with absolute path on windows,
but using their basenames, requiring the libdirs to be passed to
the linker.

This fixes undefined behaviour sanitizer on MinGW after
b8000c0ce84541c5b5535419234fb65ce77d6756.
