[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. rdar://44645820 llvm-svn: 342678

; AppleClang-700 uses a debug info version that isn't recognized by llvm.org
; compilers. However, it does produce valid bitcode which should parse without
; crashing the metadata loader.
