236bef961c Patch by Gareth Moreton 
* Fix lea optimizations which lead to more failures with -O3 and -O4 options.

 - LeaLea2Lea now checks to see if the index register is in use.
 - For both the base and index registers, RegUsedBetween is changed to
 RegModifiedBetween, since just reading the register is harmless for the
 optimisation (it finds additional optimisations in the RTL as a result).
 - Because I saw the mis-optimisation with MOVZX that occurred (even
 though it was due to the mis-optimisation of LEA instructions), I wrote
 some extra code in OptPass2Movx as a safety measure to ensure this
 doesn't happen (although no additional instances of it happening have
 been noted so far - best be safe than sorry).

2cd6951205 Apply patch proposed by J. Gareth Moreton in bug report #0038527 
The patch reworks the LeaLea2Lea optimisation and hopefully fixes the bug (admittedly by adding a brand new optimisation!).
