allow Cmp, Neg, Abs for floating point even if no_float is set: these Operations should be safe as they cannot produce more mantissa bits

when creating vfldz nodes for float unknown, place them after the frame pointer so they could be spilled ...

Fix logic error in IncSP-to-Push/Pop optimisation, which caused the optimisation to be performed exactly when it was NOT requested.

Fix inconsistency between reg_req and ins of Push: reg_req expected the stack in the fourth place and val as fith, ins said "val" before "stack".  Make the val parameter fourth and stack last to be more consistent with most other AM nodes.
