Benedikt Meurer 5fecd146bf [turbofan] Further optimize DataView accesses. 
This adds support for unaligned load/store access to the DataView
backing store and uses byteswap operations to fix up the endianess
when necessary. This changes the Word32ReverseBytes operator to be
a required operator and adds the missing support on the Intel and
ARM platforms (on 64-bit platforms the Word64ReverseBytes operator
is also mandatory now).

This further improves the performance on the dataviewperf.js test
mentioned in the tracking bug by up to 40%, and at the same time
reduces the code complexity in the EffectControlLinearizer.
