[NFC][CodeGen][AArch64] Add tests for unconditional branch duplication
c9f3288 introduced unconditional branch deduplication for basic block
sections and machine function splitting, but it didn't add tests for
AArch64 since prior behavior crashed the test.
This change adds tests for AArch64 and has no functional change.
