8de05cef85 Enable code generation for array literals. 
Introduce macro assembler support for pushing heap-object handles and
for comparing a register to a heap-object handle.

Cleanup: Remove some code that was needlessly commented out.  Added
TODO's for code that was commented out (where we do not hit an
UNIMPLEMENTED).

6b03961d4c Fix 'nm' results parsing in tickprocessor. 
Without an explicit check if a function belongs to shared library address space, "finishing" a library symbols processing with 'addPrevEntry(libEnd);' can cause emission of code entries which cover almost the entire address space, shadowing other code.

2cc6fef9d5 Fix the problem with JS entries in tickprocessor. 
The main problem was due to the following: after Erik had fixed the logger to report library addresses, tickprocessor started to add to the code map entries that covered almost entire memory. This happened because tickprocessor contains a heuristic to bias addresses of functions from dynamic libraries:

    if (funcInfo.start < libStart && funcInfo.start < libEnd - libStart) {
      funcInfo.start += libStart;
    }

And, as tickprocessor tried to process all symbols from the library, including data entries, which can be outside reported library addresses range, the second condition failed, and funcInfo.start remained unbiased.
