Xavier Leroy 558f40e344 New back-end optimization pass: common subexpression elimination (CSE).
(Reuses results of previous computations instead of recomputing them.)
(Cherry-picked from branch backend-optim.)
Tested on amd64/linux and i386/linux.
Other back-ends compile (after assorted updates) but are untested.

Xavier Leroy 29b34438e0 - Constant ropagation for float and int32/int64/nativeint arithmetic.
Constant propagation for floats can be turned off with option
  -no-float-const-prop, for codes that change FP rounding modes at
  run-time.
- Clambda / C-- / Mach: represent float constants as FP numbers of type 
  float rather than literals of type string.
- Tested for AMD64; other archs need testing.

Benedikt Meurer 3bb161216b Perform constant optimizations for integer division and modulus on the C-- level.
This way we can avoid having to duplicate the same functionality for
every backend, and we may also benefit from other optimizations performed
during C-- generation.
