codeGen: allocate small arrays of statically known size inline
codeGen: allocate small arrays of statically known size inline

This results in a 46% runtime decrease when allocating an array of 16
unit elements on a 64-bit machine.

In order to allow newArray# to have both an inline and an out-of-line
implementation, cgOpApp is refactored slightly. The new implementation
of cgOpApp should make it easier to add other primops with both inline
and out-of-line implementations in the future.
