Implemented Floating/Double-floating arithmetic operations: Add,
Substract and Multiply: FA, FS, FM, DFA, DFS, DFM respectively.
* Fixed issue in the register editor: Wrong value displayed when reading
64 bit or 128 bit registers.
* Fixed issue in the register editor: Error when writing to 128 bit
registers.
How to use the register editor:
1. Load an .ELF file
2. Select any instruction from a thread. (This is a workaround to
activate the appropriate event listener. This will be changed in the
future).
3. Press 'R' key and modify any register you want.
Note:
The register editor only works with PPU and SPU threads.
Additional changes:
* Fixed the filesize problem caused by the instruction editor dialog.
* Instruction Editor: Fixed small issue in SPU threads
