danno@chromium.org 4d23256cf9 MIPS: Add code again to allow reclaiming old unexecuted functions. 
Port r12898 (69ff6e50)

Original commit message:
When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".
