723bed3105 Optimize calls to evals. Most of the time there is no reason to 
perform a context lookup in the runtime system for the 'eval'
function. Instead load the 'eval' function from the global context in
generated code if it is not shadowed.

Will port to other platforms as a separate change.

3ec0b86495 Make StringCharCodeAt runtime function do what it name implies and not 
just indexed string access.

The difference is that String.prototype.charCodeAt accepts any number
as an index, whereas string[] only accepts array indices.

64bc39a726 Fix: make string indexing work with Infinity. 
NumberToUint32 that I was trying to use maps -0 to +0 (as desired) but
also maps +/-Infinity to +0, which made +/-Infinity a valid string
index. I fixed it by introducing a new runtime function with the right
semantics.

55e32d2f3b Introduce faster swapping primitives. 
Keyed store stub sits high in sorting profiles.

Swapping allows to save us additional type checks as we could both read and
write elmenets (on fast path) without them.

the exponent is 0.5 or -0.5 in which case we calculate the square root or

39e63f0aec Implement tagging of profiler log event blocks. 
This change allows to associate integer tags with blocks of profiler
log events, and repeat calls to 'ResumeProfiler' / 'PauseProfiler' in
order to establsh nested (not necessary properly nested) blocks. By
supporting this, we will be able to match WebInspector's CPU profiler
abilities in DevTools.

I also refactored some testing code.

3c0d77f32e Fix stack corruption when calling non-function. 
Fix for issue 603.

Revision r3484 removed the property name from the call stack for
call ICs.  When a non-function was called via a call IC and
Function.prototype.call, an extra value was left on the stack that the
caller could not know to clean up.

Fix is to change the JS builtin used for calling non-functions.  It
now gets the callee as receiver, rather than iterating stack frames
and finding it on the expression stack of its JS caller.

Currently the DefineOrRedefineAccessorProperty deletes the existing

adds a new one. This can potentially be optimized.
