[vm/compiler] Support UnboxedDouble representation in unoptimized code

In the unoptimized code unboxed double inputs are now unboxed in the
instruction prologue, and unboxed double output is boxed in the
instruction epilogue. Double values are still always boxed on the
expression stack in the unoptimized mode.

Support for unboxed doubles in unoptimized code allows us to have
one implementation of double and dart:math built-in functions,
shared across optimized and unoptimized modes.
