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.
