Improvements
* small optimisations (e.g. merging untag and cmp #0 )
* added fixed point to double conversion instructions for simpler conversions
More on the last point: a Smi can be seen as a fixed point number with the
a one bit fractional part. Fixed to double instructions allow us to convert
a Smi to a double without untagging.

Change constant pool marker to be the unconditional, permanently undefined instruction.

The previously-used instruction isn't guaranteed to always be undefined,
and the encoding used was conditional (failing the condition on an
undefined instruction is itself undefined and not guaranteed to
fault!). I would have like to use a more clever encoding (see bug 2963),
but we need the extra bits to encode the size of the constant pool.

Improve ARM-Simulator.
...
This patch
- removes the unimplemented code crash when rendering invalid/unknown instructions and prints "unknown" instead.
- prints the beginning of the constant pool marker.
- adds "da" as a shortcut for "disasm".
- print hexadecimal representation of double and single registers. This makes it easier to debug move/conversion code that uses temporary int32 values in floating point registers.
- annotates the stack with short prints of the values (HeapObjects and smis),
- makes disasm take an address or a register as second argument without a third argument, which defaults to printing ten instructions.

ARM: backend opt for ToBoolean: JIT code generation for ToBool
...
Upgraded the CodeGenerator::ToBoolean() function in the ARM backend to use complete JIT code generation and not make runtime calls to ToBool (when VFP is enabled).
This change also includes the vcmp VFP instruction that supports a constant 0.0 as the second operand.

ARM: Special code for raising to the power of an integer
...
When calculating Math.pow where the exponent is a smi use a simple loop to calculate the result.
Added support for the vmov instruction moving from one doubleword extension register to another.
Added some Math.pow tests which partially covers what is in the Sputnik tests.

ARM: Use the vsqrt instruction when available
...
vsqrt is used to calculate Math.sqrt(x), Math.pow(x, 0.5) and Math.pow(x, -0.5). Code size doesn't matter, as %_MathSqrt and %_MathPow are only called in one place each.
