This is a new static flag system, designed to have all flags in a central place, and compiled into the binary without requiring static constructors for registration.  All flags are moved out of the specific modules and into flags.defs, with different sections for debug, release, etc.  The flag variables are always defined.  For example, a debug flag in release mode still exists, but is read only and set to the default value.

- Simplified frame entry and frame exit code.
- Added ArgumentsAdaptorTrampoline and check for matching argument counts in the InvokePrologue.
- Removed definition and uses of USE_OLD_CALLING_CONVENTIONS.
- Changed MacroAssembler::InvokeBuiltin to match ia32 version.
- Start introducing convenience instructions in the ARM assembler as needed. These instructions take all Register parameters to avoid extra typing of "Operand(reg)".


To keep the architectures in sync these changes have been made to the ia32 files:
- Changed MacroAssembler::EnterFrame(StackFrame::Type type) to MacroAssembler::EnterInternalFrame().


These parts are still missing:
- unimplemented: Builtins::Generate_FunctionApply - large limit
- unimplemented: Builtins::Generate_ArgumentsAdaptorTrampoline - non-function call
- The files have not been lint'd yet.

__ push(eax);
to enable push/pop eliminations.

__ push(eax) must happen before RecordWrite because RecordWrite may destroy 
eax value. To be safe, also moved __ push(r0) on ARM to above RecordWrite.

This only affects the case where a context variable is used in a inner scope.

Create a tests for it. It fails if __ push(eax) is after RecordWrite.

generated library 18% smaller.

Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.

Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.

Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.

Improved ARM support by fixing the write barrier code to use aligned loads and stores and by removing premature locals optimization that relied on broken support for callee-saved registers (removed).

Refactored the code for marking live objects during garbage collection and the code for allocating objects in paged spaces. Introduced an abstraction for the map word of a heap-allocated object and changed the memory allocator to allocate executable memory only for spaces that may contain code objects.

Moved StringBuilder to utils.h and ScopedLock to platform.h, where they can be used by debugging and logging modules. Added thread-safe message queues for dealing with debugger events.

Fixed the source code reported by toString for certain builtin empty functions and made sure that the prototype property of a function is enumerable.
