78226352b7 Ensure HAllocateObject always allocates in new-space. 
This is needed so that we can start removing write-barriers in optimized
code if we can prove that the receiver object is always in new-space.

f14b93a508 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.

f00631b710 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.

1a356cff3e Fix redefinition of aliased elements in arguments. 
This refactors the way we (re)define elements to perform normalization
and attribute updating at a much deeper level, thereby removing some
bogus special cases in upper runtime layers.

Most element setters take an indicator flag that distinguishes between
setting and defining. Setting of an element causes attributes to remain
unchanged, writability to be checked and callbacks to be called.
Defining of an element causes attributes to be updated and callbacks to
be overridden. The same approach could be taken for properties.

b90a8ec851 Enable test-api/TurnOnAccessCheckAndRecompile and change it so it can't cause a GC. 
A GC in the access check callbacks NamedSecurityCallback and IndexedSecurityCallback
violates the contract about these callbacks.

Added a EXTERNAL VMState scope around the call to FailedAccessCheckCallback to be
consistent with the other callback invocations.

1336b913d0 Make built-ins strict mode conforming, and support a --use-strict flag. 
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.

One consequence is that the properties on the builtin object  are no longer
non-writable, and I had to adapt one test. Is that a problem?

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

Also removed dead flag code in Compiler::Compile.

bd79e299e5 Uniformly handle 'undefined' store to Float64Array and Float32Array. 
Previous behavior diverged in ICs and Crankshaft. When storing to a Float32Array or Float64Array, the ICs treated undefined as zero while Crankshaft treated it as NaN. Now both ICs and Crankshaft treat it as NaN, which is consistent with the WebGL & ECMAScript spec.
