ART: Speed up stack guard page install Only the main thread doesn't have its stack mapped in under normal conditions. Reading each page is a lot of overhead and we should try to avoid it. Rewrite to first try a (non-fatal) protect. If the outcome is a success, finish. Otherwise do the stack mapping, and try again. Bug: 27718174 Change-Id: I16b214567585ed2f09970f618ccdec7eed219fd3
