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.

The heavy version is for x86 and x64.  The light version
is for ARM and MIPS.  Remove the elements_ array from the
virtual frame in the light version.  More simplifications

Otherwise page header check is not quite robust: if there is a smi
at the same offset as Page::is_normal_page field, wrong result would
be returned.

That shouldn't be the problem for paged spaces as objects in those
pages do not span page boundaries and thus cannot mess with ::is_normal_page field.

I did not implement tests covering calls with undetectable parameters since I would need to make these tests native. Just thought it was not worth the effort. If you think tests would make sense, I can add them. We might want to allow other functions to receive undetectable parameters, but I am not seeing any good candidates.
