34d6ff7606 Implemented missing pieces of the debugger for ARM. 
The main piece of this change was to add support for break on return for ARM. On ARM the normal js function return consist of the following code sequence.

  mov sp, fp
  ldmia sp!, {fp, lr}
  add sp, sp, #4
  bx lr

to a call to the debug break return entry code using the following code sequence

  mov lr, pc
  ldr pc, [pc, #-4]
  <debug break return entry code entry point address>
  bktp 0

The values of Assembler::kPatchReturnSequenceLength and Assembler::kPatchReturnSequenceLength are somewhat misleading, but they fit the current use in the debugger. Also Assembler::kPatchReturnSequenceLength is used in the IC code as well (for something which is not related to return sequences at all). I will change that in a separate changelist.

For the debugger to work also added recording of the return sequence in the relocation info and handling of source position recording when a function ends with a return statement.

Used the constant kInstrSize instead of sizeof(Instr).

Passes all debugger tests on both simulator and hardware (only release mode tested on hardware).

bcff52624d Cleaned up some debugger stuff on ia32 and x64. 
Got rid of the debug break on return entry code which did not add anything. It just jumped directly to the debug break on return code.

Removed the CodePatcher class on x64 as it was not implemented.

Added instruction cache flush to where the return sequence was patched on x64.

Added some missing ENABLE_DEBUGGER_SUPPORT #ifdef/#endif.

ae062d5df1 Added new scope type ScopeIterator::ScopeTypeCatch for with generated from catch blocks. 
Removed a false assertion in ScopeIterator that assumed context extension to never be a JSContextExtensionObject.

The context extension object in a 'with' context is JSContextExtensionObject iff the 'with' statement is generated from a catch block in order to extend its local scope with a variable holding exception object. This is how we differentiate 'catch' scope from 'with' scope.

def729b6ad Change to limit the amount of space we waste due to fragmentation 
in old space. Before this change we would compute the fragmentation 
limit before the GC, but that means that we take all the garbage 
into account - and consequently we almost never hit the limit (because 
we have a lot of garbage).

This change changes the policy to compact on the *next* GC if we
determine that we have too much fragmentation after doing a GC.
We'll do a GC if we've wasted more than 1MB and more than 15% of
the old space size.

This can be further improved by computing whether or not to compact
during the marking phase.

abbe98b959 Use different output directories when building using the Visual Studion solution.The different Visual Studio solutions for building for the different architures ia32, x64 and arm (simulator) now use separate output directories. Debug/Release for ia32, Debug64/Release64 for x64 and DebugArm/ReleaseArm for arm (simulator).It was required to duplicate all the project files for arm to avoid output from ia32 and arm to get mixed.
