Parsing some kinds of integers and junk values in Runtime_NumberToString. For that values the string is converted into int and then into SMI. It lets to avoid floating point operations.

StringToInt rewritten. This version doesn't allocate memory for long decimals and uses percise rounding if radix 10 or a power of 2 (in other cases rounding error still may occur). Handling special values moved from Runtime_StringParseInt into StringToInt in order to make it consistent with StringToDouble.

The stack check has been moved from the Accept function dispatching on
the AST node type, earlier to the Visit function dispatching on the
visitor type.

This allows very simple non-recursive visitors (not taking extra
arguments or returning values) via the convention of calling "Visit"
if one wants the stack check and "Accept" if one does not.  Recursive
calls should all be via "Visit".

CopyWords cannot actually copy zero words---it'd clobber destiantion with
the first word of source.

Add an ASSERT to check this condition plus update array builtins to verify
for amount of copied data when necessary.

Rounding happens when the number exceeds 53 bits of floating point mantissa. Current implemetation ignores digits after some limits. 0x1000000000000081 was rounded to 0x1000000000000100 while 0x100000000000008000001 was rounded to 0x100000000000000000000.

The flow graph has been simplified to remove the special branch, join,
and exit nodes.  All nodes are now basic blocks (possibly empty to
preserve edge-split form) with a distinguished entry and exit block.

Most trivial expressions are not added to the flow graph as
instructions.  The assigned variable analyzer has been changed to
sometimes work right-to-left so that right subexpressions can be
marked as trivial.

The reaching definitions analysis has been temporarily removed, and
the analyses that depended on it (primitivity analysis, dead code
marking) as well.

 * Faster hashing for sequential strings.

 * When adding short external two-byte strings try to convert them
   back to ascii. Chances are high the embedder uses two-byte
   representation even for ascii strings. This optimization saves
   memory and makes hashing faster.
