ia32: Fuse map and type checks in call ICs for API functions.
...
This uses the fact that if a map stayed the same then the object
still passes the type check. A new builtin is added to handle the
API call in this case.

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.

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.

Don't pass the "at start" parameter to native RegExp
...
As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.
The x64 version have been tested on both Linux and 64-bit Windows Vista.
For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.

First step of refactoring expression contexts in the toplevel code
...
generator.
Contexts are no longer stored in the AST but in the code generator's
state. This means that the running the code generator selector is not
required to use the toplevel code generator (for instance, if we
already know that we can and should use it).
