[PATCH] D28041: IR: Module summary representation for type identifiers; summary test scaffolding for lowertypetests.

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a subscriber: llvm-commits.
pcc added a dependency: D28014: Support: Add YAML I/O support for string maps..

Set up basic YAML I/O support for module summaries, plumb the summary into
the pass and add a few command line flags to test YAML I/O support. Bitcode
support to come separately, as will the code in LowerTypeTests that actually
uses the summary. Also add a couple of tests that pass by virtue of the pass
doing nothing with the summary (which happens to be the correct thing to do
for those tests).

Depends on https://reviews.llvm.org/D28014
