I have updated the target options. Space-saving is now enabled by
-Os. There is also a new option -msim to enable building for the
simulator (the simulator is pending submission to gdb-binutils).

I have fixed the Texinfo formatting.

FT32 is a new high performance 32-bit RISC core developed by FTDI for embedded applications.

Support for FT32 has already been added to binutils. This patch adds FT32 support to gcc.
        
Please can someone review it, and if appropriate commit it, as I do not have write access to the tree.
