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.

| 80 // 4810578: varargs unsafe on 32-bit integer/64-bit pointer architectures | |
| 81 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in | |
| 82 // system header files. On 32-bit architectures, there is no problem. | |
| 83 // On 64-bit architectures, defining NULL as a 32-bit constant can cause | |
| 84 // problems with varargs functions: C++ integral promotion rules say for | |
| 85 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a | |
| 86 // varargs function it will remain 32-bits. Depending on the calling | |
| 87 // convention of the machine, if the argument is passed on the stack then | |
| 88 // only 32-bits of the "NULL" pointer may be initialized to zero. The | |
| 89 // other 32-bits will be garbage. If the varargs function is expecting a | |
| 90 // pointer when it extracts the argument, then we have a problem. | |
| 91 // | |
| 92 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0. | |
