9c105f0940 Force full GC whenever CollectAllGarbage is meant to trigger a full GC. 
Add a finalize incremental marking mode for CollectAllGarbage to finalize incremental marking when incremental marking is in progress, but we want a full gc at a given CollectAllGarbage call site.

Default mode for CollectAllGarbage is finalize incremental marking and perform a full GC.

f236777bfe [x64] Use xorl to materialize smi zero. 
Before we always loaded smi zero via a movabs with a 64-bit immediate,
which is pretty expensive compared to the xorl.

8ad33d6db6 PPC: [turbofan] Load immortal heap objects from the heap roots. 
Port 5d2de78a77

Original commit message:
It's cheaper to materialize heap constants by loading from the roots
array instead of embedding the constant into the instruction stream, at
least on x64, arm and arm64.

Drive-by-fix: Also cleanup the materialize constant from frame
optimization.

219f4a9eb4 Avoid modifying the real context chain for debug evaluation. 
Instead of modifying a context chain and then modifying it back, causing
potential mismatches, we clone the inner context chain and evaluate
the expression in this cloned context. We then copy all local variable
values back if needed.

31a3d5fcd2 X87: Disable the test case for X87 since f3338dd3b0 
The overwrite-builtins test cases will throw one expected exception
  and the exception message should include the source position in the JS
  file. But crankshaft compiler does not generate the source position for
  it when creating the flow graph by default. The source position information
  is always zero. So it failed when comparing with the reference file.

  If we use crankshaft compiler on IA32 platform to run this test case, it
  has the same failure.
