This patch adds a singleton that tracks recently freed code range
regions and provides hints for newly created code ranges such that
the freed addresses are reused.
This is a workaround for the CFG leak described in the linked bug.

Port 5fecd146bf
Original Commit Message:
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.

Previously, when given a log with few ticks, the timeline would lump
them all into one or two buckets. This patch allows ticks to be assigned
to buckets more sparsely.
This patch also fixes a bug where there was a gap on the right side of
the timeline, which also caused the function tick marks to be slightly
misaligned. This was more noticable with fewer buckets.

The DataView access methods can use the neutering protector to avoid
introducing an explicit check into the optimized code to see if the
backing store was neutered. Instead the optimized code has an implicit
dependency on the global neutering protector which gets invalidated
when the first array buffer is neutered (globally). We use the same
trick for typed arrays already.
