[libcxx-commits] [libcxx] [libc++][test] XFAIL sized deallocation tests for AIX, z/OS, and MinGW (PR #98960)

[Xing Xue via libcxx-commits]

https://github.com/xingxue-ibm created https://github.com/llvm/llvm-project/pull/98960

The sized deallocation test cases fail on AIX, z/OS, and MinGW because they default to `-fno-sized-deallocation`. This patch XFAILs these test cases for the affected targets. Once they change the default, we will get `unexpectedly pass`.
