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.

Add -with-frame-pointers to ./configure

This option can be used to tell the native compiler that it should
update frame pointers, so that debuggers and profiling tools
(especially Linux perf) can use them. For now, it is only supported
by the Unix/amd64 port.

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).
