Revert "Revert "Fix deoptimization with pending exception""
This reverts commit 6e2d5747d00697a25251d25dd33b953e54709507.
Fixes the deoptimization path from compiled code (generated by the
Optimizing compiler) by adding wrapper artDeoptimizeFromCompiledCode.
This wrapper, called through the matching assembler stub
art_quick_deoptimize_from_compiled_code, pushes the deoptimization
context just before deoptimizing the stack.
