  [libunwind][test] Add test to check for unw_resume()

This is here for local unwinding, which unw_resume() restores
the machine state and then directly resumes execution in the
target stack frame.

  Log Message:
  -----------
  [libunwind][LoongArch] Restore $r1 before $r4 in `jumpto`

$ra should be restored before $a0, otherwise the baseaddress ($a0) would
be destroyed. See file `UnwindRegistersSave.S` for reference.

This also makes libcxx and libcxxabi regtest pass for the `-DLIBCXXABI_USE_LLVM_UNWINDER=ON` build.
