Removing unused default switch cases in switches over enums that already account for all enumeration values explicitly.
...
(This time I believe I've checked all the -Wreturn-type warnings from GCC & added the couple of llvm_unreachables necessary to silence them. If I've missed any, I'll happily fix them as soon as I know about them)

Remove SetWorkingDirectory from the Process interface. Nothing in LLVM
...
or Clang is using this, and it would be hard to use it correctly given
the thread hostility of the function. Also, it never checked the return
which is rather dangerous with chdir. If someone was in fact using this,
please let me know, as well as what the usecase actually is so that
I can add it back and make it more correct and secure to use. (That
said, it's never going to be "safe" per-se, but we could at least
document the risks...)

target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.
