fd1ace4d94 X87: Fixed flooring division by a power of 2, once again... 
port r21769

original message:
    Avoid right shifts by zero bits: On ARM it actually means shifting by
    32 bits (correctness issue) and on other platforms they are useless
    (performance issue). This is fix for the fix in r20544.

We're basically trading undefined behavior for implementation defined
behavior, which should be OK for UBSan. :-) The generated code should
be identical, at least I checked that for GCC 4.6.3 on x64.

649057e05c Remove forced type changes when they can't deopt 
Hydrogen attempts to force representation changes on certain operations in order
to deoptimise on the change rather than the operation. However, these forced
changes are often unnecessary on 64-bit platforms, and cause poor code
generation, so this patch makes some of them conditional on whether it's
possible for deoptimisation to occur in the change.

On ARM64, this prevents sequences like:
                  ;;; <@46,#89> smi-tag
0x7ff282c7f050   144  lsl x4, x4, #32
                  ;;; <@48,#90> smi-untag
0x7ff282c7f054   148  asr x5, x4, #32
                  ;;; <@50,#31> mul-const-i-s
0x7ff282c7f058   152  lsl w6, w5, #3

b0b10ec72d MIPS: Fixed flooring division by a power of 2, once again... 
Port r21769 (52e191b)

Original commit message:
Avoid right shifts by zero bits: On ARM it actually means shifting by
32 bits (correctness issue) and on other platforms they are useless
(performance issue). This is fix for the fix in r20544.
