5267d7b884 Introduce JSFunction::EnsureHasInitialMap method. 
This change enforces explicit allocation of the initial map for each
JSFunction to introduce a proper layering between the JSFunction class
and the Heap class. A follow-up change will then handlify the two
functions AllocateInitialMap and AllocateFunctionPrototype.

bdeaf7514a Enable preaging of code objects when --optimize-for-size. 
This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.

19b2ee1c40 Handlify PropertyCell::SetValueInferType and friends. 
This finally gets rid of the pesky trampoline in SetValueInferType and
enforces the layering between PropertyCell and Heap. It requires full
handlification of NewGlobalObject as well, which is only used when the
snapshot is created at compile-time.

f0305bd83e Instance-type-related fixes and cleanup. 
Things got quite a bit out of sync (don't we all love copy-n-paste?):

   * TypeToString didn't handle SLICED_STRING_TYPE,
     SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
     JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.

   * INSTANCE_TYPE_LIST was missing entries for
     SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.

To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.

Removed INVALID_TYPE on the way, it had no real use.

63defee477 First implementation of allocation elimination in Hydrogen. 
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.

This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.
