VM: Share object pool entries for optimized static calls.

Independently patchable entries are not required for debugging because breakpoints are only added to unoptimized code, nor for deopt because deopt patches the instruction stream and not the object pool.

Future work: Reduce the static call table from (pc offset, function, code) triples to (pc offset, function or allocation stub) pairs.

Lgtm.

For precompiled code we should investigate switching to direct calls of statics.
