Cheats with the 0xC1 and 0xC2 type instructions don't work

[shocoman]

The 0xC1 and 0xC2 instructions don't work. Their usage just completely crashes a game.

Here is one not working cheat as an example:

C2000000 00000010
00000000 00000000
00000000 E12FFF1E

The problem lies in these two lines: one & two. The instruction adr lr, exec_function_return overwrites the LR reg, but its original value is not backed up anywhere. In the end, the cheat routine will try to return through this clobbered up register here and fail.

As a solution, it seems enough to just add the LR reg to the push and pop lists at the start and the end of the cheat engine routine. Nitrohax kinda does it
