[NewPM] Second attempt at porting ASan This is the second attempt to port ASan to new PM after D52739. This takes the initialization requried by ASan from the Module by moving it into a separate class with it's own analysis that the new PM ASan can use. Changes: - Split AddressSanitizer into 2 passes: 1 for the instrumentation on the function, and 1 for the pass itself which creates an instance of the first during it's run. The same is done for AddressSanitizerModule. - Add new PM AddressSanitizer and AddressSanitizerModule. - Add legacy and new PM analyses for reading data needed to initialize ASan with. - Removed DominatorTree dependency from ASan since it was unused. - Move GlobalsMetadata and ShadowMapping out of anonymous namespace since the new PM analysis holds these 2 classes and will need to expose them.

; Test that ASan runs with the new pass manager
[test] Fix test failure The version mismatch symbol is version 9 on 32 bit android. Since this test isn't actually testing any android specific functionality, we force the target triple to x86_64-unknown-unknown in order to have a consistent version number. It seems the test was already trying to do this, just not doing it right Patch by Christopher Tetrault Differential Revision: https://reviews.llvm.org/D68882 llvm-svn: 374836

[NewPM] Add explicit triple to test This prevents warnings like: > warning: overriding the module target triple with x86_64-apple-darwin on macOS. llvm-svn: 354008
