[PATCH] D36429: [clang-import-test] Option to dump the IR for an expression

[Sean Callanan via Phabricator via cfe-commits]

spyffe created this revision.

This adds the argument `--dump-ir` to `clang-import-test`, which allows viewing of the final IR.   This is useful for confirming that structure layout was correct.

I've added an XFAILed test that exercises this, checking that a struct defined inside a function body has the right fields.  Currently it does not because `LookupSameContext()` (ExternalASTMerger.cpp) can't find the struct.  This is an issue I intend to resolve separately.
