356cf1ed0a RegExp: Add support for table-based character class 
code generation.  This is performance neutral for
all our tests, but a factor 6 faster for the Unicode
based regexp in the new test (and much more compact
code).

a3eccef3fa Valgrind cleanliness, part 1: Delete current isolate on exit. 
Currently we leak 140kB from 80 allocation sites when we evaluate a simple
"print(1+2)" in d8 and exit. This might not be a real problem in Chrome because
most of the time the whole process containing v8 vanishes, but it can hide real
leaks in a sea of false positives. Therefore, this CL and a few subsequent ones
clean this up a bit.

This simple CL alone fixes 45 leaks, leaving only 35 with a net loss of 2192
bytes (on ia32).

5bca664574 MIPS: Improve polymorphic loads on single slots. 
Port r11132 (91bdad6108).

Original commit message:

If all property lookups for a polymorphic load actually result in the
same field index under all maps, we can actually emit a monomorphic load
that is guarded by a map check that verifies that the actual map is in
the set of handled maps. This also allows GVN to get rid of redundant
such map checks.

4cb600962f 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.
