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.

Lazily save double registers for HCallRuntime instructions within Hydrogen code stubs.
...
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.

Re-land "Add methods to enable configuration of ResourceConstraints based on limits derived at runtime."
...
Adds ConfigureResourceConstraintsForCurrentPlatform and SetDefaultResourceConstraintsForCurrentPlatform which configure the heap based on the available physical memory, rather than hard-coding by platform as previous. This change also adds OS::TotalPhysicalMemory to platform.h.
The re-land fix the performance regression caused by accidental change in default max young space size.
