Teresa Johnson 778af35f66 Use a different block id for block of metadata kind records ... Summary: There are currently two blocks with the METADATA_BLOCK id at module scope. The first has the module-level metadata values (consisting of some combination of METADATA_* record codes except for METADATA_KIND). The second consists only of METADATA_KIND records. The latter is used only in the METADATA_ATTACHMENT block within function blocks (for metadata attached to instructions). For ThinLTO we want to delay the parsing of module level metadata until all functions have been imported from that module (there is some bookkeeping used to suture it up when we read it during a post-pass). However, we do need the METADATA_KIND records when parsing the function body during importing, since those kinds are used as described above. To simplify identification and parsing of just the block containing the metadata kinds, use a different block id (METADATA_KIND_BLOCK_ID). Support older bitcode without the new block id as well.
