[compiler-rt] Move ASan non-Linux-specific tests out of the Linux/ directory

[kubamracek]

Summary

I noticed that several testcases in the test/asan/TestCases/Linux/ directory are not really Linux specific. The following tests from the Linux directory pass on OS X 10.10:

• glob.cc
• glob_test_root
• heap-overflow-large.cc
• heavy_uar_test.cc
• interception_failure_test.cc
• new_array_cookie_test.cc
• new_array_cookie_uaf_test.cc
• new_array_cookie_with_new_from_class.cc
• tsd_dtor_leak.cc

Let's move them one directory up, so they are run on other platforms as well.

This test should go to TestCases/Posix. Sooner or later we'll start to run tests from TestCases on Windows.

test/asan/TestCases/interception_failure_test.cc

3

I'm not sure this works on Windows. Timur?

test/asan/TestCases/new_array_cookie_test.cc

1

This is also not implemented for Windows

test/asan/TestCases/tsd_dtor_leak.cc

8

This test is also Posix-specific.

test/asan/TestCases/interception_failure_test.cc

I don't know. If this is an important feature, I'm fine if you put it into the directory with common tests and I'll take a look later when I get my hands to enabling these tests on Windows.

[kubamracek]

Moving the new_array_*, tsd_dtor_leak.cc, glob.cc to Posix.

[samsonov]

LGTM, Please watch for the buildbots after the commit. I hope that these tests will work on FreeBSD, but don't have confidence in it. Thanks for doing this!

interception_failure_test.cc

(On Diff #16298)

Wow, glad to hear this test works on Mac.

[kubamracek]

Landed in r222486.

I hope that these tests will work on FreeBSD, but don't have confidence in it.

Some of them do not pass, but let's consider them one by one.
