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#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.

The rational behind this change is that for the ARM instruction sets, the
valid range for address offsets depends on the type of data being loaded
or stored.
