[PATCH] D40527: [libclang] Record parsing invocation to a temporary file when requested by client

[Alex Lorenz via Phabricator via cfe-commits]

arphaman created this revision.

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.
