[libclang] Record parsing invocation to a temporary file when requested by client This patch extends libclang by allowing it to record parsing operations to a temporary JSON file. The file is deleted after parsing succeeds. When a crash happens during parsing, the file is preserved and the client will be able to use it to generate a reproducer for the crash. These files are not emitted by default, and the client has to specify the invocation emission path first. rdar://35322543 Differential Revision: https://reviews.llvm.org/D40527 llvm-svn: 319702

[libclang] Store unsaved file hashes when recording parsing invocations Storing the contents of unsaved files is too expensive. Instead a hash is stored with a record invocation. When a reproducer is generated, Clang will compare the stored hashes to the new hashes to determine if the contents of a file has changed. This way we'll know when a reproducer was generated for a different source to the one that triggered the original crash. rdar://35322543 llvm-svn: 319729

Fix one more record-parsing-invocation.c test issue on Windows Lit's env should be used before not. Sean Eveson pointed out the right solution. Thanks! llvm-svn: 319836
