[PATCH] D38462: [DebugInfo] Replace unreachable with ReportError in debug frame parser.

[Jonas Devlieghere via Phabricator via llvm-commits]

The parser should not rely on assertions or unreachables for invalid
input. This patch replaces calls to llvm::unreachable with calls to
ReportError in the debug frame parser.

This fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3519
Test case is taken from there.
