Fix some register names in the ia32 disassembler.  Byte register and XMM register names were sometimes not used, or used where they shouldn't be.

On ARM the break at break slots wrongly used the break at return stub which assumes an object opinter in r0. At break slots there are no objects live in registers so a GC while at a break on a break stub could cause a crash as r0 was wrongly pushed on a internal frame to be handled by GC.

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.

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.

Ensure that there is always enough bytes between consequtive calls in optimized code to write a call instruction at the return points without overlapping.

Add a call to deoptimize all functions after running tests with --stress-opt. This will catch some issues with functions which cannot be forcefully deoptimized. Some of the tests failed on ARM with that change without the rest of the changes in this change.
