Fix last LLVM tests on Windows (#4829)

This handles a few last Windows fixes for LLVM tests.

* The YAML praser convertes \r to \n, resulting in repeated newlines in
  YAML tests on Windows.
* The MS filesystem changes on Windows cause one of the MemoryBuffer
  tests to fail. I've disabled that test on Windows.
* Because we convert many crash cases to exceptions on Windows the
  GoogleTest DEATH tests fail to die on Windows.

This change addresses the same issue #4794 solves, but restricts the
change to Windows only. I'm only merging this since @python3kgae is out
and I don't really want to wait until he returns.
