e98e7c9f41 MIPS: Lazily save double registers for HCallRuntime instructions within Hydrogen code stubs. 
Port r17044 (94843cc)

Original commit message:
Right now we eagerly save all allocatable double registers upon
entry to every Hydrogen code stub that uses HCallRuntime, and
restore them when we return. Since the HCallRuntime is on the
fallback path for code stubs, this is both a waste of time and
stack space in almost every case.

This patch adds a flag to the HCallRuntime, which controls whether
the instruction saves the double register itself (using the save
doubles flag for the CEntryStub), or whether its up the surrounding
code to handle the clobbering of double registers.

208890d118 Print out how many AllocationMementos were found on a scavenge of new 
space. This is useful because the unrooted mementos affect heap
decisions like pretenuring mode, and helps to gauge the effectiveness
of allocation-site feedback.

3f461303bd Disable externalization of sliced/cons strings in old pointer space. 
This is a temporary workaround for the fact that a good deal of the code that triggers access checks, which in turn externalize strings, is not yet handlified and therefore not GC safe.
