D68049 created options for basic block sections: -fbasic-block-sections=, -funique-basic-block-section-names. Rename options in llc and lld (--lto-) to be consistent. Specifically,
- Rename basicblock-sections to basic-block-sections
- Rename unique-bb-section-names to unique-basic-block-section-names
Further, add a test to lld for --lto-basic-block-sections= and --lto-unique-basic-block-section-names.
