various fixes and enhancements
* correct refmap->oopmap conversion (register numbering, stack slot numbering)
* fixes for inlining (correct scoping in exception handler lookup, NPE in scope conversion)
* support for "jump to runtime stub" (patching code needs to be aware of jmp instruction)
* provide more information about methods (to allow inlining: has_balanced_monitors, etc.)
* fixes to signature type lookup
* isSubTypeOf: correct handling of array classes
* RiType: componentType/arrayOf
* prologue: inline cache check, icmiss stub
* klass state check (resolved but not initialized) in newinstance
* card table write barriers
* c1x classes are optional (to allow running c1 without them)
* correct for stored frame pointer in calling conventions (methods with arguments on stack)
* getType(Class<?>) for some basic types, used for optimizations and folding
* RiMethod/RiType: throw exception instead of silent failure on unsupported operations
* RiType: resolved/unresolved array type support
* refactoring: new on-demand template generation mechanism
* optimizations: template specialization for no_null_check, given length, etc.
