3515559a38 Increase old space in cctest/test-api/HugeConsStringOutOfMemory test. 
This test is failing on MIPS since r11715 (a7d6f92c),
it seems that after the modifications in bootstrapper.cc,
this test runs out of old generation space on MIPS.

19ece2bec8 Enable lazy compilation for non-trivial outer contexts. 
This changes the compiler to be more aggressive about lazy compilation
of closures with non-trivial outer context. Compilation can only be
triggered with a valid outer context now. One exception is the debugger,
which can request compilation of arbitrary shared code, but it ensures
to trigger compilation only at points where no context is needed.

31a0d0257c Serialize edge counts instead of indexes in heap snapshot. 
The serialized node structure currently holds an index
of its first containment edge in the edges array.
The index can be quite big (up to 7 digits for large snapshots).
The patch changes the serialization format to pass
node containment edge count instead. For most nodes the count
is just a single digit number.
This reduces serialized snapshot size and therefore its transfer time.

e4c472a7af Implement correct checking for inherited readonliness on assignment. 
Removes 6 out of 8 of our remaining unintentional failures on test262.

Also fixes treatment of inherited setters added after the fact.

Specifically:

- In the runtime, when looking for setter callbacks in the prototype chain,
  also look for read-only properties. If one is found, reject (exception in
  strict mode). If a proxy is found, invoke proper trap.
  Note: this folds in the CanPut function from the spec and avoids an extra
  lookup over the prototype chain.

- In generated code for stores, insert a test for the maps from the prototype
  chain, but only up to the object where the property already exists (which
  may be the object itself).
  In Hydrogen, if the found property is read-only or not cacheable (e.g. a
  proxy), bail out; in a stub, generate an unconditional miss (to get an
  exception in strict mode).

- Add test cases and adapt existing test expectations.
