RFR: 8310606: Fix signed integer overflow, part 3

[Dean Long]

Most of these changes are straight-forward, but these could use some explaining:

AllocatePrefetchDistance was accessed before it's dynamic constraint function got run.  I changed it to use static constraints.

RangeCheckEliminator::update_bound(): for constant bounds with meaningless values, bail out.  For X + c bounds, use Java wrap-around semantics.

-------------

Commit messages:
 - use java_add/subtract/negate where appropriate
 - use java_negate
 - used unsigned add to avoid signed overflow
 - avoid integer overflow in multiply
 - use static constraint for AllocatePrefetchDistance
