TSX/RTM

[aw27]

This is the RTM counterpart of the HLE published yesterday.

Unlike the HLE, for RTM you will need a TSX supported CPU or the Intel CPU emulator.

I followed closely what the TSX developer of GCC has done here:
https://github.com/andikleen/tsx-tools/blob/master/locks/spin-rtm.c
because I could not find a better example.

BTW, I found a solution for the problem of the program terminating before all threads (in last topic about TSX/HLE) being done. This demo uses that  solution.
