Vedant Kumar 7840e607b9 [Bitcode] Address backwards compat bug in r342631 ...

r342631 expanded bitc::METADATA_LOCATION by one element. The bitcode
metadata loader was changed in a backwards-incompatible way, leading to
crashes when disassembling old bitcode:

  assertion: empty() && "PlaceholderQueue hasn't been flushed before being destroyed"
  Assertion failed: (empty() && "PlaceholderQueue hasn't been flushed before being destroyed")

This commit teaches the metadata loader to assume that the newly-added
IsImplicitCode bit is 'false' when not present in old bitcode. I've added a
bitcode compat regression test.
