The block_size seems to be not reliable, even after trying to more closely match the interpreter by looking at the analysis for (addr+opcode->size-1) for detecting the end of the block. Since we need to "calculate" this number shortly before returning to RunForCycles, it seemed logical to use the (up to now) unused return value of the blocks. Improves SMG2 here. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6266 8ced0084-cf51-0410-be5f-012b33b47a6e
