Added caching for resolved types and resolved fields.
This is crucial, because the local load elimination will lead to wrong results, if field equality (of two RiField objects with the same object and the same RiType) is not given. The caching makes sure that the default equals implementation is sufficient.

| 25 // Events and EventMark provide interfaces to log events taking place in the vm. | |
| 26 // This facility is extremly useful for post-mortem debugging. The eventlog | |
| 27 // often provides crucial information about events leading up to the crash. | |
| 28 // | |
| 29 // All arguments past the format string must be passed as an intptr_t. | |
| 30 // | |
| 31 // To log a single event use: | |
| 32 // Events::log("New nmethod has been created " INTPTR_FORMAT, nm); | |
| 33 // | |
| 34 // To log a block of events use: | |
| 35 // EventMark m("GarbageCollecting %d", (intptr_t)gc_number); | |
| 36 // | |
| 37 // The constructor to eventlog indents the eventlog until the | |
| 38 // destructor has been executed. | |
| 39 // | |
| 40 // IMPLEMENTATION RESTRICTION: | |
| 41 // Max 3 arguments are saved for each logged event. | |
| 42 // | |
