26a8dc3818 ARM: Make the ARM hardware builder green 
Fix a bug in the --debug-code alignment check in the C entry stub.

Don't force the --debug-code flag in the ARM disassembler tests. The framework does support passing flags and the test runner will when running tests in debug mode.

Skip some deserialization tests which crashes from time to time.

0e183035a2 ARM: Merging constants in simulator and assembler header files and other cleanup. 
First stab at a general ARM cleanup patch. It merges ARM constants so that they can be used across simulator, assembler and disassembler, and tidies up some syntax and ambiguities.

99a5b9f713 ARM: Initial type recording binary operation stub 
This implements the type recording binary operation stub for ARM. This first iteration only supports ADD. Handling of 32-bit integers is currently not implemented but just transitions. The generic case for now delegates to the generic binary operation stub.

161d631b5e Change ARM exit frame layout and alingment handling 
Change the ARM exit frame to have the same layout as the IA32 exit frame. This basically re-arranges the order of fp and sp and changes the sp location of the entry frame to hold the sp used by the gc and not the sp for popping the arguments. This removes the option of tearing down the frame and returning using one ldm instruction.

The main motivation for this is to avoid pushing an alignment word before generating the entry frame. The GC handling of optimized frames process the registers pushed as part of a safepoint and asumes that these are at the top of the frame, so if an alignment word is pushed this processing will be one off.

The alignment handling in the C entry stub have also been simplified. Now the value of lr is stored to a stack slot already reserved avoiding pushing it and keeping track of "frame skew".

This does result in more instructions in the exit frame on ARM, but we can look into improving this later.

8a9eeaf8da Reapply change to with/arguments interaction. 
This is svn r6415 with a bugfix.

The bug was that we can have scopes with 0 heap slots (functions with
such scopes do not need a local context) and scopes with at least
Context::MIN_CONTEXT_SLOTS.  The code generator only allocated a local
context if there were strictly more than Context::MIN_CONTEXT_SLOTS.
Before the change to with/arguments, it was impossible to actually get
a function scope with exactly Context::MIN_CONTEXT_SLOTS because every
such scope included a heap-allocated arguments (and arguments shadow)
slot.

2b7596a516 Instanceof slow case bind is incorrect. 
Currently, the bind for the slow label is after the pushing of the
args registers which renders the args pushing dead code because there
is a Ret preceeding it. The comments also imply that the arg pushing
should be part of the InvokeBuiltins tail call.

be5763fc4d Cleanup the way the debugger stores live registers when entering at a break 
The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max).

This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it.

Fix a missing live register when breaking at ARM keyed load.
