Prepare DefinePropertyAccessor for callback transitions.
Although things are currently OK here, in the future it won't be enough to check
for the existence of a CALLBACKS result, we must additionally check that it
actually contains an accessor. In a nutshell: 'sed s/IsFound/IsProperty/' once
again...
Additionally, the control flow in DefinePropertyAccessor has been simplified by
using a helper function.

Improve performance of keyed loads/stores which have a HeapNumber index.
Some GWT compiled code results in array access that has a heap number (e.g. -0)
as an index. Until now this would result in a generic IC.
For example:
a[-0] === a[0] or
a[0.25 * 4] === a[1]
This change detects heap numbers that are representable as a smi
and converts them. As a result we can still use the fast keyed monomorphic
ICs. Optimized code already handles keyed access with a double-key efficiently.
As a result the frame rate on the reported benchmark improves by roughly 2x.

Regexp: Improve the speed that we scan for an initial point where a non-anchored
regexp can match by using a Boyer-Moore-like table. This is done by identifying
non-greedy non-capturing loops in the nodes that eat any character one at a time.
For example in the middle of the regexp /foo[\s\S]*?bar/ we find such a loop.
There is also such a loop implicitly inserted at the start of any non-anchored
regexp.
When we have found such a loop we look ahead in the nodes to find the set of
characters that can come at given distances. For example for the regexp
/.?foo/ we know that there are at least 3 characters ahead of us, and the sets
of characters that can occur are [any, [f, o], [o]]. We find a range in the
lookahead info where the set of characters is reasonably constrained. In our
example this is from index 1 to 2 (0 is not constrained). We can now look 3
characters ahead and if we don't find one of [f, o] (the union of [f, o] and
[o]) then we can skip forwards by the range size (in this case 2).
For Unicode input strings we do the same, but modulo 128.
We also look at the first string fed to the regexp and use that to get a hint
of the character frequencies in the inputs. This affects the assessment of
whether the set of characters is 'reasonably constrained'.
We still have the old lookahead mechanism, which uses a wide load of multiple
characters followed by a mask and compare to determine whether a match is
possible at this point.

http://codereview.chromium.org/9179012 was trying to achieve. This
time I am going for 80% of the benefit with around 5% of the complexity.
It works by reducing the size of the first page in each space. Unlike the
previous change there is no attempt to grow pages, we just allocate more
full-sized pages when we need more memory. For this reason the first pages are
not quite as small (compare
http://codereview.chromium.org/9179012/diff/1/src/snapshot.h with the changes
