Please review,

Test is provoking stack overflow errors and is running with 
deoptimzeALot. The recently added method 
"look_for_reserved_stack_annotated_method(...)" will traverse the stack 
and encounter an deoptimized frame that triggers 
"assert(CodeCache::find_blob_unsafe(_pc) == _cb, "inconsistent");". It 
fails on deoptimzed frames where the pc is patched and need to be 
changed to use raw_pc() to work correctly.
