HotSpotResolvedObjectType: implement hasFinalizeSubclass() correctly
don't use the (wrong) cached value, but ask the runtime on each request.
Fixes regression on xml.* benchmarks @ specjvm2008. The problem was:
After the constructor of Object was deoptimized due to an assumption violation,
it was recompiled again after some time. However, on recompilation, the value
of hasFinalizeSubclass for the class was not updated and it was compiled again
with a, now wrong, assumption, which then triggers deoptimization again.
This was repeated until it hit the recompilation limit (defined by
PerMethodRecompilationCutoff), and therefore only executed by the interpreter
from now on, causing the performance regression.

575 // Implementation of AdapterHandlerLibrary | |
576 // | |
577 // This library manages argument marshaling adapters and native wrappers. | |
578 // There are 2 flavors of adapters: I2C and C2I. | |
579 // | |
1748 | 580 // The I2C flavor takes a stock interpreted call setup, marshals the |
581 // arguments for a Java-compiled call, and jumps to Rmethod-> code()-> | |
582 // code_begin(). It is broken to call it without an nmethod assigned. | |
583 // The usual behavior is to lift any register arguments up out of the | |
584 // stack and possibly re-pack the extra arguments to be contigious. | |
585 // I2C adapters will save what the interpreter's stack pointer will be | |
586 // after arguments are popped, then adjust the interpreter's frame | |
587 // size to force alignment and possibly to repack the arguments. | |
588 // After re-packing, it jumps to the compiled code start. There are | |
589 // no safepoints in this adapter code and a GC cannot happen while | |
590 // marshaling is in progress. | |
0 | 591 // |
592 // The C2I flavor takes a stock compiled call setup plus the target method in | |
593 // Rmethod, marshals the arguments for an interpreted call and jumps to | |
594 // Rmethod->_i2i_entry. On entry, the interpreted frame has not yet been | |
595 // setup. Compiled frames are fixed-size and the args are likely not in the | |
596 // right place. Hence all the args will likely be copied into the | |
597 // interpreter's frame, forcing that frame to grow. The compiled frame's | |
598 // outgoing stack args will be dead after the copy. | |
599 // | |
600 // Native wrappers, like adapters, marshal arguments. Unlike adapters they | |
601 // also perform an offical frame push & pop. They have a call to the native | |
602 // routine in their middles and end in a return (instead of ending in a jump). | |
603 // The native wrappers are stored in real nmethods instead of the BufferBlobs | |
604 // used by the adapters. The code generation happens here because it's very | |
605 // similar to what the adapters have to do. | |
