Summary: `llvm-bcanalyzer` prints out the stream type of the file it is analyzing. If the file begins with the LLVM IR magic number, it reports a stream type of "LLVM IR". However, any other bitstream format is reported as "unknown". Add some checks for two other common bitstream formats: Clang AST files, which begin with 'CPCH', and Clang serialized diagnostics, which begin with 'DIAG'. Test Plan: `check-llvm` Reviewers: pcc, aprantl, mehdi_amini, davide, george.karpenkov, JDevlieghere Reviewed By: JDevlieghere Subscribers: JDevlieghere, bruno, davide, llvm-commits Differential Revision: https://reviews.llvm.org/D41979 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@330529 91177308-0d34-0410-b5e6-96231b3b80d8
