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.

problem.

Fabrice Le Fessant 1b2667b9f2 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.

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).

The wretched MacOSX "ld -shared" (under 10.6 at least) balks on
subtracting two local labels, while it deigns subtracting two
nonlocal labels.
