[NFC] Fix formatting for the 'aix-ld.c' test case.

[stevewan]

Summary

Based on comments received in D80415 pertinent to test case format, the following fixes are provided to other tests in 'aix-ld.c' for the sake of consistency and readability,

• Align flags in RUN directives vertically.
• Align patterns in CHECK directives vertically.
• Remove the ‘-o %t.o’ as it’s unnecessary for tests with ‘-###’.
• Fix typos in comments.

[stevewan]

Fix misalignment caused by tab.

[stevewan]

Pass 'clang-format' checking.

[hubert.reinterpretcast]

LGTM with minor comment.

clang/test/Driver/aix-ld.c

8

The two-space indent for continuations on a pipeline or similar boundary was intentional. We're only somewhat okay here because the non-terminal commands are all multiline deep indentation. I think we should retain the two-space indent.

54–59

Good catch.

[stevewan]

Add the two-space indent before continuations on a pipeine.

[hubert.reinterpretcast]

LGTM.
