442cb7c21a Fix compile failure with GCC 4.5.0 (issue 1244) 
GCC apparently assumes that given that we do a static cast in the next
line the value must actually be in StrictModeFlag enum range (even
though this is actually what we are asserting)

fa9e57e326 Change __defineGetter__ and __defineSetter__ to respect non-configurable. 
This makes us compatible with firefox. Earlier on we were somehow
compatible with safari - which will allow defining a getter even when
an existing getter is present and non-configurable. We would, however,
in addition to overwriting the getter also change configurable to
true. The approach used by firefox seems much more sound, i.e., why
should it be possible to use __defineGetter__ or __defineSetter__ to
overwrite a non-configurable getter or setter respectively.

I will file a bug on the webkit bugtracker.

d31594feae Refactor construction of switch statements to avoid subgraphs. 
Refactor construction of switch statements so it doesn't use class
HSubgraph.

There are also a few improvements.  We do not use an auxiliary list of
comparisons because they're embedded as a linked list in the graph
under construction.  We share a common break block for all breaks from
the same switch.  We do not insert empty blocks unless necessary to
maintain edge-split form.

There is also a bug fix.  The entry to a clause body is a potential
join and must have a join ID set, otherwise deoptimization within the
body can go to an unpredictable place in the unoptimized code.

Non-moveable code-stube are allocated in large object space. They are only required on ARM where the different C-entry stubs are required to never move.

This gets rid of pre-computing these stubs and hope that they never move. Also for crankshaft the C-entry stub which saved doubles is not generated in the snapshot so it ends up being generated at runtime and potentially move.

927f341d3c Strict mode arguments do not share binding with formal parameters. 
Move strict mode flag from TemporaryScope to Scope so that it can be accessed from variable binding code.
Arguments do not alias in strict mode (ia32, x64 and arm, codegen and full codegen).
Hydrogen tolerates null arguments_shadow().
In codegen-<arch> arguments object is allocated eagerly to capture values before they get modified.

This avoids problems when getters/setters are defined on Object.
