[Bitcode][NFC] Add abbrev for FUNC_CODE_DEBUG_LOC (#147211)
DILocations that are not attached to instructions are encoded using
METADATA_LOCATION records which have an abbrev. DILocations attached to
instructions are interleaved with instruction records as FUNC_CODE_DEBUG_LOC
records, which do not have an abbrev (and FUNC_CODE_DEBUG_LOC_AGAIN
which have no operands).
Add a new FUNCTION_BLOCK abbrev FUNCTION_DEBUG_LOC_ABBREV for
FUNC_CODE_DEBUG_LOC records.
This reduces the bc file size by up to 7% in CTMark, with many between 2-4%
smaller.

(go to stage1-ReleaseLTO-g).
This optimisation is motivated by #144102, which adds the new Key Instructions
fields to bitcode records. The combined patches still overall look to be a
slight improvement over the base.
