The two tests (S8.5_A2.1, S8.5_A2.2) fail on ia32 Linux and simulators.
They do pass on ARM and MIPS hardware under Linux, and on the other
supported platforms and architectures.

They are now marked PASS || FAIL_OK.

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.

da5b44cbd1 Add support for Mac OS X 64bit builds with GYP
Note that in order to build for 64bits mode, you'll have
to specify the target architecture explicitely, the default
is still 32bits for Mac OS X.

Example with make and gcc:

$ export GYP_GENERATORS=make
$ make dependencies
$ make -j 8 library=shared x64.release

Example with make and clang:

$ export GYP_GENERATORS=make
$ export CC=/usr/bin/clang
$ export CXX=/usr/bin/clang++
$ export GYP_DEFINES="clang=1"
$ make dependencies
$ make -j 8 library=shared x64.release

Example with xcode:

$ export GYP_GENERATORS=xcode
$ build/gyp_v8 -Dtarget_arch=x64
$ xcodebuild -project build/all.xcodeproj -configuration Release

63f033576c Fix performance regressions due to lazy initialization.
This CL:
- Adds a new trait parameter to LazyInstance to let it initialize the instance
  without paying the cost of atomic operations (which are expensive on Mac).
  This only works for users who don't care about thread-safety and this is now
the default initialization trait used by LazyInstance in v8.

- 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.
That lets the math functions get rid of CallOnce().

automatic way of bumping the existing Test262 revision without deleting
the data directory manually.
