f712e12f98 6830717: replay of compilations would help with debugging 
When java process crashed in compiler thread, repeat the compilation process will help finding root cause. This is done with using SA dump application class data and replay data from core dump, then use debug version of jvm to recompile the problematic java method.

ab725dba1d 7003554: (tiered) assert(is_null_object() || handle() != NULL) failed: cannot embed null pointer 
C1 with profiling doesn't check whether the MDO has been really allocated, which can silently fail if the perm gen is full. The solution is to check if the allocation failed and bailout out of inlining or compilation.
