[Openmp-commits] [openmp] [OpenMP][AIX] Fix test config for AIX (PR #88272)

[Xing Xue via Openmp-commits]

https://github.com/xingxue-ibm created https://github.com/llvm/llvm-project/pull/88272

This patch fixes the test config so that it works for `tasking/omp50_taskdep_depobj.c` which uses different flags to test with compiler's `omp.h`.
* set test environment variable `OBJECT_MODE` to `64` if it is set explicitly to `64` in the AIX environment. `OBJECT_MODE` is default to `32` and is recognized by AIX compilers and toolchain. In this way, we don't need to set `-m64` for all compiler flags for 64-bit mode
* add option `-Wl,-bmaxdata` to 32-bit `test_openmp_flags` used by `tasking/omp50_taskdep_depobj.c`

Subject: [PATCH] Set OBJECT_MODE and add -bmaxdata for test_openmp_flags in
 32-bit mode.
