8df50f2622 ARM: Implement inline conversion of heap numbers to int32 values for bitoperations.
For bit operations, values are truncated and converted to the range -2^31 through 2^31 - 1. This patch provides inlined handling of this conversion for all heap numbers.

Before, we were calling runtime for every heap number that did not fit into a signed int32.

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.

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.

a8b41a0edd Fix bug in X64 RegExpExec stub.
