1 * exceptions: handle exceptions inside unmanaged code
2 * exceptions: save/restore floating point state
3 * implementet all floating point instruction in x86.brg, we also need to check
4 the floating branch instruction - some of them seems to be wrong, we need to
5 write better tests for that.
7 * correctly align value types on the stack and in arrays
8 * enum types can have several base types (not only int32)
9 * document the functions and variables in the JIT
10 * implement a register set for FP registers (just count register usage on x86)
