ART: Throw StackOverflowError in native code Initialize stack-overflow errors in native code to be able to reduce the preserved area size of the stack. Includes a refactoring away from constexpr in instruction_set.h to allow for easy changing of the values. Bug: 16256184 (cherry picked from commit 7ea6f79bbddd69d5db86a8656a31aaaf64ae2582) Change-Id: I117cc8485f43da5f0a470f0f5e5b3dc3b5a06246

Fix stack overflow for mutual recursion. There was an error where we would have a pc that was in the method which generated the stack overflow. This didn't work however because the stack overflow check was before we stored the method in the stack. The result was that the stack overflow handler had a PC which wasnt necessarily in the method at the top of the stack. This is now fixed by always restoring the link register before branching to the throw entrypoint. Slight code size regression on ARM/Mips (unmeasured). Regression on ARM is 4 bytes of code per stack overflow check. Some of this regression is mitigated by having one less GC safepoint. Also adds test case for StackOverflowError issue (from bdc). Tests passing: ARM, X86, Mips Phone booting: ARM Bug: https://code.google.com/p/android/issues/detail?id=66411 Bug: 12967914 Change-Id: I96fe667799458b58d1f86671e051968f7be78d5d (cherry-picked from c0f96d03a1855fda7d94332331b94860404874dd)

Adding old unit tests to test suite. These tests are copied straight over. They'll still run, but they're using the old system. Change-Id: If494519e52ddf858a9febfc55bdae830468cb3c8
