This test was reenabled on 32-bit Arm in #181071, but it still fails.

Below are the "original" and "new" thread frames, that differ in number, causing the assert error above:
```
Original:
frame #0: 0x0ac80658 a.out`baz at main.c:5:3
frame #1: 0x0ac8067c a.out`bar at main.c:10:10
frame #2: 0x0ac8069c a.out`foo at main.c:15:10
frame #3: 0x0ac806c8 a.out`main at main.c:20:10
frame #4: 0xea83d7d6 libc.so.6`
frame #5: 0xea83d886 libc.so.6`__libc_start_main + 94
frame #6: 0x0ac80570 a.out`_start + 40

New:
frame #0: 0x00000000 my_custom_baz [synthetic]
frame #1: 0x00000000 my_custom_bar [synthetic]
frame #2: 0x00000000 my_custom_foo [synthetic]
frame #3: 0x00000000 my_custom_main [synthetic]
```

Start with lldb/test/API/functionalities/scripted_frame_provider/pass_through_prefix/TestFrameProviderPassThroughPrefix.py, especially test_pass_through_with_prefix, and reproduce it using the failing LLDB API test command on 32-bit Arm. Compare the original and new frame lists in the failure log; done means the pass-through test preserves the expected frame count and the full test file passes on Linux Arm.
