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.

- 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.

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.

PR#5933 type-specialize 'let compare = compare' on ints and strings
...
According to the reporter 'sliquister', type-specialized comparison
can nearly halve compilation time in some cases. This patch applies
type-specialization throughout the OCaml distribution sources, so not
all changes will have performance utility, but in this case I think
it's best to be consistent, as I see no downside to the change.
