Implement fast code for the common cases of left hand sides that are less than three times larger as the right hand side and and right hand sides that are powers of two up and including 32.
...
In the covered special cases the result is computed directly, else the generic stub is called. The implementation deoptimizes only for mod 0 and if the result may be a negative zero.

Make 'with' mark only variables occurring in the body as used.
...
Before, we conservatively marked every variable in a scope as used if the
scope contained 'with'. Instead, just mark the variables occurring in the
body of the with. This avoids marking 'arguments' as used whenever 'with'
occurs, which incurs an extra performance penalty (a use of arguments is
seen as an instruction to redirect all parameter accesses to the arguments
object).

Support StringCharCodeAt in hydrogen/lithium.
...
This patch adds H- and L-variants of StringCharCodeAt and StringLength.
StringCharCodeAt is used to inline a constant function call of
String.prototype.charCodeAt and to implement the corresponding inline
runtime function. It does not yet use the recently introduced extra IC
state. (We can specialize on string encoding and avoid deopts because
of out of bounds accesses.)
StringLength needs more work because the stub version of it also
supports strings wrappers and it matters in some cases. (We have to
separate the string only case.)

Truncate rather than round to nearest when performing float-to-integer

conversions for external array types, which implement the Typed Array
spec. The new code paths are for SSE3 and SSE2 capable processors.
The code for non-SSE2 processors is unchanged for now. The ARM port
appears to already be correct.
Moved the generation of the external array load and store intrinsics
to the stub cache (on all platforms) so that they are generated at run
time and can take advantage of CPU features.
This functionality is covered by the array-unit-tests.html test in the
WebGL conformance test suite:

https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/array-unit-tests.html

each in turn. Tested in Chromium on 32-bit Mac OS X and 64-bit Linux.
