  -----------
  [libunwind] [SEH] Clear DISPATCHER_CONTEXT when initializing a cursor

We only initialize a few fields in DISPATCHER_CONTEXT - don't leave
the rest in an uninitialized state; make sure the whole struct is
in a deterministic state.

This makes nondeterministic failures deterministic, for some cases
relating to forced unwinding on aarch64/arm (which requires filling
in parsing of the xdata for finding the exception handler and LSDA).

  Log Message:
  -----------
  [compiler-rt] [test] [asan] Skip the static asan testsuites on mingw targets

Mingw only provides a dynamically linked CRT (contrary to
MSVC/clang-cl), so it is expected that the static asan test
configuration doesn't work.

Skip adding these test suites in mingw configurations.
