2016-05-24[ThinLTO] Change ODR resolution and internalization to be index-basedTeresa Johnson1-194/+272
Summary: This patch changes the ODR resolution and internalization to be based on updates to the Index, which are consumed by the backend portion of the transformations. It will be followed by an NFC change to move these out of libLTO's ThinLTOCodeGenerator so that it can be used by other linkers (gold and lld) and by ThinLTO distributed backends. The global summary-based portions use callbacks so that the client can determine the prevailing copy and other information in a client-specific way. Eventually, with the API being developed in D20268, these may be modified to use information such as symbol resolutions, supplied by the clients to the API.

Summary: This patch turns on LoopUnrollAnalyzer by default. To mitigate compile time regressions, I chose very conservative thresholds for now. Later we can make them more aggressive, but it might require being smarter in which loops we're optimizing. E.g. currently the biggest issue is that with more agressive thresholds we unroll many cold loops, which increases compile time for no performance benefit (performance of those loops is improved, but it doesn't matter since they are cold). Test results for compile time(using 4 samples to reduce noise): ``` MultiSource/Benchmarks/VersaBench/ecbdes/ecbdes 5.19% SingleSource/Benchmarks/Polybench/medley/reg_detect/reg_detect 4.19% MultiSource/Benchmarks/FreeBench/fourinarow/fourinarow 3.39% MultiSource/Applications/JM/lencod/lencod 1.47% MultiSource/Benchmarks/Fhourstones-3_1/fhourstones3_1 -6.06% ``` I didn't see any performance changes in the testsuite, but it improves some internal tests.
