The opt_manage framework didn't really do much except assuring that some
analysis info is computed before a pass starts. We can achieve this
simpler by providing an assure_irg_properties function.
This commit also fixes some places where analysis info was potentially
not invalidated before.

Noone was really using the return values anyway. This change makes the
API more consistent.

graph_properties are things that a transformation may destroy but which
can be easily recalculated.

graph_constraints are set after lowering phases have been running and
forbid certain constructs that no (later) transformation is allowed to construct

The new interface uses no complicated callbacks anymore, but is a simple
ir_node* -> void* nodemap. Adapted all users of ir_phase for this.

some were missing anyway and nobody is using the global declarations anyway

Converted: ifconv, boolopt, combo, fpvrp, ldst, code placement,
jumpthreading, deconv, parallelize mem, loop, scalar replacement,
cfopt.

convopt: fix potential bug with modulo shifts, improve cost calculation for optimizable conv(shift) combinations

Create the in array before the node is constructed instead of copying the in array an set the operands afterwards.
