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.

Rename HBranch (the instruction that coerces an arbitrary HValue to
control flow) to HTest to free up the term Branch to refer to any
control instruction with two successors.

Change the virtual FirstSuccessor and SecondSuccessor functions on
control instructions to a pair of data members.

Add a generic tagged version for all bitwise operation that
invoke the generic stub. This allows us to perform generic
bitwise operations (i.e. on non-integers) without deoptimizing.

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).

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.)

We hit an assertion failure when we tried to record the AST ID of
the (shared) .arguments variable proxy more than once.  This was hit
when we had multiple calls to the same parameter in a function that
used the arguments object.  The fix is to not visit the subexpressions
of the (shared) property access expression.

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

Manually verified all of the SSE3/SSE2/non-SSE2 code paths by enabling
each in turn. Tested in Chromium on 32-bit Mac OS X and 64-bit Linux.
