Xavier Leroy 3ce32fba4f Wrong MASM syntax, try again.

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.

Gabriel Scherer 75b8c0184f 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.

Benedikt Meurer 6fad047cc0 PR#5181: Merge common floating point constants in ocamlopt. 
Instead of generating a unique quadword constant for each and every
floating point constant use within a function, we now collect the floating
point constants on a per-module basis, and generate only one quadword
per floating point constant.

This affects only the amd64 and i386 ports (both Unix/Linux/OS X and Windows).
