      MIPS64: Port `Remove weak-list of optimized JS functions.` on BE · 93e00066
      sreten.kovacevic authored 
      Port f0acede9
Original commit message:
`This CL removes the weak-list of JS functions from the context
and all the code that iterares over it. This list was being used
mainly during deoptimization (for code unlinking) and during
garbage collection. Removing it will improve performance of
programs that create many closures and trigger many scavenge GC
cycles.

No extra work is required during garbage collection. However,
given that we no longer unlink code from JS functions during
deoptimization, we leave it as it is, and on its next activation
we check whether the mark_for_deoptimization bit of that code is
set, and if it is, than we unlink it and jump to lazy compiled
code. This check happens in the prologue of every code object.

We needed to change/remove the cctests that used to check
something on this list.

Working in x64, ia32, arm64, arm, mips64 and mips.`

On mips64 big endian flags are in upper part of register.

      Adjust SP delta for kArchSaveCallerRegisters case · 0eb1bc9b
      Albert Mingkun Yang authored 
      In kArchSaveCallerRegisters, PushCallerSaved alone alters stack pointer
without informing `frame_access_state`. This commit compensate the
inconsistency by manually increasing the delta after pushing registers.
This affects systems (currently only ARM64) using stack pointer for
accessing variables stored on stack.
