6093d0dbf5 Inline NumberToString 
NumberToString in runtime JavaScript is inlined through a call to a stub. Currently the stub only checks the number string cache and only if the number is a smi. Code is shared with the inlining of number string cache lookup when adding a smi to a string.

638cb4f91d Always load the JavaScript builtins code entry from the JavaScript 
function instead of baking in the address of the first one that we see
in code.

This removes the need for fixups processing and makes the stubs safe
when there is no natives cache and therefore multiple versions of the
builtin functions.

9b5c312bfc Initial implementation of fast path operation for bitwise OR. 
Support a binary operation (bitwise OR) so long as it's not nested in
the left subexpression.  This ensures that the expression stack never
has height greater than two and so can be kept fully in registers.

The bounded expression stack height and the absence of any side
effects on the fast path allows us to still bailout out to the very
beginning of the function if any of our fast-path checks fail.

2f0f6face1 Fast compiler: Load globals variables directly from property cells. 
This is a first step towards loading globals directly from property cells instead
of going through a load IC.

This change supports only properties with the DontDelete attribute since
we are only able to bailout into the generic code generated by the secondary 
code generator the beginning of a function. The resulting fast-case code is 
specialized for a specific context. When invoked with a different global object, 
it will always bailout to the secondary code.

When loading a property that does not exist at compile-time or a property
that is deleteable we still generate the generic load IC.
