  compiler-rt: Make the tests pass on AArch64 and with page size != 4096.

This makes the tests pass on my AArch64 machine with 16K pages.

Not sure why some of the AArch64-specific test failures don't seem to
occur on sanitizer-aarch64-linux. I could also reproduce them by running
buildbot_cmake.sh on my machine.

  Changed paths:
    M compiler-rt/test/msan/dtls_test.c

  Log Message:
  -----------
  Switch dtls_test.c from XFAIL to UNSUPPORTED on aarch64.

It passes on some buildbots, so we can't expect failure.

  Log Message:
  -----------
  dfsan: Fix test with gcc 15.

With gcc 15 we end up emitting a reference to the
std::__glibcxx_assert_fail function because of this change:
https://github.com/gcc-mirror/gcc/commit/361d230fd7800a7e749aba8ed020f54f5c26d504
combined with assertion checks in the std::atomic implementation.

This reference is undefined with dfsan causing the test to fail. Fix it
by defining the macro that disables assertions.
