The code was not properly getting the variable addresses and using the offset and address fields of the .data section. Fix all of that, and update the tests. Bug: 145162678 Test: Unit tests pass. Test: ./art/test/run-test --dex2oat-jobs 4 --host --prebuild --compact-dex-level fast --jit --no-relocate --runtime-option -Xcheck:jni 137-cfi Test: ./art/test/testrunner/testrunner.py -t 137 --host Change-Id: Ic61c4487334fd2273cda9c56eb1a3b525a03edb7
