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.

Reduce initial boot-up memory use. This is an other attempt at what
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
in spaces.cc in this cl): We want to be able to do a little bit of allocation
before we have to add a full-sized page to the space.

This only works for users who don't care about thread-safety and this is now

- Reverts the changes that were made in r11010 in isolate.{cc,h}. That lets
Isolate's accessors be as cheap as they were before (but adds one static initializer).
- Adds OS::PostSetup() used to initialize the math functions which depend on CPU features.

Make setting of accessors even more atomic.
Now the whole getter/setter/attributes triple gets created/set together,
avoiding any hacks regarding previous values/attributes, making things a lot
simpler.
While doing this, an interesting problem surfaced, which has been there for a
long time: After adding/changing acessors in slow mode, we could potentially
fail going back to fast mode because of a failed memory allocation, signaling
the need for a GC. But we have already changed the object in slow mode, so we
are not idempotent and the retry would trigger a newly inserted assertion
(namely, that the code obeys access restrictions). This has been solved by
splitting the transformation to fast mode from the actual setting of the
accessors.

When running with --always-opt, don't deoptimize named loads with uninitialized type feedback.
This avoids tests taking too long because of repeated deoptimizations.

MIPS: Branch delay slot and other optimizations.
List of changes:
-added a minor optimization to the Simulator that quickly skips nops in the delay slot
-slightly re-worked CEntryStub to save a few instructions
CEntryStub now expects the following values:
-s0: number of arguments including receiver
-s1: size of arguments excluding receiver
-s2: pointer to builtin function
Two new MacroAssembler functions were added to make usage more convenient:
-PrepareCEntryArgs(int num_args) to set up s0 and s1
-PrepareCEntryFunction(const ExternalReference&) to set up s2
-removed branch delay slot nops from the most frequently used code areas
-reorganized some code to execute fewer instructions
-utilized the delay slot of most Ret instructions
This does not cover all Rets, only the most obvious cases.
Also added a special version of DropAndRet that utilizes the delay slot.
-added some comments to code areas where explanation of the register/delay slot usage may be needed
-added an optimization to Jump so it doesn't always pre-load the target register

The failing mozilla test was caused by more deoptimizations
introduced by --always-opt and r11087.

We already do this for binary-ops, unary-ops and comparisons. Typefeedback for named loads can now also
