| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On host, when there is a crash, the code tries to do an unwind from the signal handler. Under some conditions this can require a stack larger than 16K, so increase this value to 32K. The symptom of this is that you get an empty backtrace running art tests when there is a crash.

This is a cherry pick from aosp/master which fixes several issues. Most notably: * It enables generation of ELF-64 on 64-bit systems (in dex2oat, C compilers already produce ELF-64). Libunwind requires ELF-64 on 64-bit systems for backtraces to work. * It enables loading of ELF files with dlopen. This is required for libunwind to be able to generate backtrace of current process (i.e. the process requesting backtrace of itself). * It adds unit test to test the above (32 vs 64 bit, in-proces vs out-of-process, application code vs framework code). * Some other fixes or clean-ups which should not be of much significance but which are easier to include to make the important CLs cherry-pick cleanly.
